.7 Define the sampling distribution of the mean.
*9.8 Specify three important properties of the sampling distribution of the mean.
9.9 Indicate whether the following statements are true or false. If we took a random sample of 35 subjects from some population, the associated sampling distribution of the mean would have the following properties:
(a) Shape would approximate a normal curve.
(b) Mean would equal the one sample mean.
(c) Shape would approximate the shape of the population.
(d) Compared to the population variability, the variability would be reduced by a factor equal to the square root of 35.

(f) Variability would equal the population variability.
*9.13 Given a sample size of 36, how large does the population standard deviation have to be for the standard error to be
(a) 1?
(b) 2?
(c) 5?
(d) 100?
*9.14 (a) A random sample of size 144 is taken from the local population of grade-school children. Each child estimates the number of hours per week spent watching TV. At this point, what can be said about the sampling distribution?
(b) Assume that a standard deviation, σ, of 8 hours describes the TV estimates for the local population of schoolchildren. At this point, what can be said about the sampling distribution?
(c) Assume that a mean, µ, of 21 hours describes the TV estimates for the local population of schoolchildren. Now what can be said about the sampling distribution?
(d) Roughly speaking, the sample means in the sampling distribution should deviate, on average, about ___ hours from the mean of the sampling distribution and from the mean of the population.
(e) About 95 percent of the sample means in this sampling distribution should be between ___ hours and ___ hours.

*10.9 The normal range for a widely accepted measure of body size, the body mass index (BMI), ranges from 18.5 to 25. Using the midrange BMI score of 21.75 as the null hypothesized value for the population mean, test this hypothesis at the .01 level of significance given a random sample of 30 weight-watcher participants who show amean BMI = 22.2 and a standard deviation of 3.1.
*10.10 Let’s assume that, over the years, a paper and pencil test of anxiety yields a mean score of 35 for all incoming college freshmen. We wish to determine whether the scores of a random sample of 20 new freshmen, with a mean of 30 and a standard deviation of 10, can be viewed as coming from this population. Test at the .05 level of significance.
*10.11 According to the California Educational Code (http://www.cde.ca.gov/ls/fa/sf/pegui-demidhi.asp), students in grades 7 through 12 should receive 400 minutes of physical education every 10 school days. A random sample of 48 students has a mean of 385 minutes and a standard deviation of 53 minutes. Test the hypothesis at the .05 level of significance that the sampled population satisfies the requiremen
*10.12 According to a 2009 survey based on the United States census (http://www.census.gov/prod/2011pubs/acs-15.pdf), the daily one-way commute time of U.S. workers averages 25 minutes with, we’ll assume, a standard deviation of 13 minutes. An investigator wishes to determine whether the national average describes the mean commute time for all workers in the Chicago area. Commute times are obtained for a random sample of 169 workers from this area, and the mean time is found to be 22.5 minutes. Test the null hypothesis at the .05 level of significance.

*12.7 In Question 10.5 on page 191, it was concluded that, the mean salary among the population of female members of the American Psychological Association is less than that ($82,500) for all comparable members who have a doctorate and teach full time.
(a) Given a population standard deviation of $6,000 and a sample mean salary of $80,100 for a random sample of 100 female members, construct a 99 percent confidence interval for the mean salary for all female members
(b) Given this confidence interval, is there any consistent evidence that the mean salary for all female members fall below $82,500, the mean salary for all members? Answers on page 435.
* 12.8 In Review Question 11.12 on page 218, instead of testing a hypothesis, you might prefer to construct a confidence interval for the mean weight of all 2-pound boxes of candy during a recent production shift.
(a) Given a population standard deviation of .30 ounce and a sample mean weight of 33.09 ounces for a random sample of 36 candy boxes, construct a 95 percent confidence interval.
(b) Interpret this interval, given the manufacturer’s desire to produce boxes of candy that, on the average, exceed 32 ounces.
*12.10 Imagine that one of the following 95 percent confidence intervals estimates the effect of vitamin C on IQ scores:
| 95 % confidence interval | Lower Limit | Upper Limit |

(b) Which one implies the largest sample size?
(c) Which one most strongly supports the conclusion that vitamin C decreases IQ scores?
(d) Which one would most likely stimulate the investigator to conduct an additional experiment using larger sample sizes? Answers on page 436.
Case Treatment Strategy Paper Instructions
Your assignment is to develop a treatment strategy for the Williams family bases on the case study provided. This paper should not be a treatment plan with DSM diagnoses. Neither should it be a verbatim report of a counseling session. Rather, this paper must articulate a plan of intervention for the family that uses a community counseling approach. Imagine that you are the community counselor, that you have conducted two counseling sessions, and now you want to develop a cohesive treatment strategy for the entire family (Jeff, Sandy, Jacob and Leo). Your job is to provide a plan of action that will assist them in moving toward healing and recovery. The community counseling model will serve you well and enable you to assist the family with the multiple issues that you will see in the case. You need to hypothesize and critically assess what is going on within the family. Consider the following questions when planning your paper:
· Based upon what you are able to deduct from the case study and assessment of issues that may have gone unsaid, where would you–as the community mental health counselor–begin?
· What are the various, obvious, or hidden issues that you believe this family experience?
· What are the best practices for addressing their needs and issues?
· What services might you be able to provide?
· What additional services would you need to find for the family?
Your paper must be 10-12 pages (not including title page, abstract, or reference page; however, these are required as well). You must use current APA style (write in third person) and integrate references to at least 10 recent scholarly sources. Ideally, include both June & Black and Scott & Wolfe in a meaningful way. You must also use scholarly journal articles to support your assessment and various treatment recommendations. Include the following content, using appropriate headings:
1. Introduce the Williams family and provide a brief case conceptualization.
2. Describe the services that you/your community counseling agency will provide.
3. Identify services that you feel could be better provided by other agencies or organizations. These need to be actual services that are offered in your community. You need to disclose the organization, its location, the cost involved, the criteria needed for referral/approval, and contact information. If some of the needed services are not available in your local community, you have to find the closest ones that the family may, realistically, use.
The Case Treatment Strategy Paper is due 11:59 p.m. (ET) on Sunday of Module/Week 5.

Colleague 1: S
In the case of Eboni and her family, we can learn the impact of adultism which young people. Adultism is described as, adults or other authority figures, who oppress the young (Adams et al., 2013). Young people are expected to follow, the rules and regulations that are made by family, schools and other authoritative figures, but many of these circumstances lead young people being oppressed (Adams et al., 2013).
Eboni presents as an African-American teen, college bound, and pregnant which is unplanned (Plummer, Makris & Brocksen, 2014). While watching the video of Eboni and her friend’s interaction, we learn that Eboni confided in the school social worker. Where she revealed her pregnancy, felt “attacked” for becoming pregnant and jumping to conclusions before getting all of the information, the encounter had a lack of empathy (Laureate Education, 2013). Eboni’s mother, on the other hand, doesn’t want Eboni to make the same mistakes that she did, when she was Eboni’s age, furthermore, she does not want Eboni to become another statistic, her mother is pushing for her to have an abortion (Laureate Education, 2013). Eboni’s father is a religious man and has his opinion about the pregnancy and what Eboni needs to do (Plummer, Makris & Brocksen, 2014). All of the adults in Eboni’s life have, told her what the what her to do, but all of this information is overwhelming, and making her even more unsure of what to do. Furthermore, none for the adults in Eboni’s life and consulted with her, asking what she wants to do.
Eboni does not want to disappoint either of her parents, as she looks up to them. But is also does not want to make a decision, that she is going to regret for the rest of her life either. Regarding oppression, the exposure, and experience that people have while they are young will impact the rest of their lives and interactions than have with others (Adams et al., 2013). Eboni is going to have to make some hard decision and at the end of the day, not everyone in her family is going to be happy with the decision she makes. Regarding class and privilege, when Eboni was born she was a statistic being born to an unwed teenage mom. Eboni wants to rise above this and break the cycle.
Part 1—Create a title page.
1. Create a title page using current APA format, and include the title of your paper, your name, your university affiliation, a running head, and page numbers.
2. Use the following pages of this document as a guide for what the style should look like for the pages of your document.
Part 2—Write a 3–4-page paper that addresses each of the following components.
1. What have you learned about factors related to success in online education from reading the articles by Waschull (2005) and Roper (2007)?
2. How can you specifically incorporate these factors related to online success in this course?
3. Roper (2007) indicated that students who were successful noted that they designated (in advance) specific times to read, complete assignments/quizzes, and interact with classmates. Using this as a foundation, develop a specific weekly plan that you can follow that details when you will complete the requirements of this course. Include each of the following in your plan:
o Review the requirements outlined in the Syllabus and Course Schedule and write a weekly plan/timetable that designates times when you will read each module/week, when you will review/study, when you will complete discussion boards/assignments, and when you will complete quizzes.
o Reflect on your roles and responsibilities to family, work, and life, and discuss how those will interact with the fulfillment of your plan outlined above. Describe your plan for designating time to this course considering those responsibilities.
o Create a table that outlines a sample module/week and how you have designated time to your varying responsibilities.
