Business Statistics

For these project assignments throughout the course you will need to reference the data in the ROI Excel spreadheet. Download it here. Using the ROI data set: 1. For each of the 2 majors test the hypothesis at the 5% significance level: The mean �Cost� for a college is $160,000. Be sure to interpret your results. 2. For Business versus Engineering majors conduct a two sample test of the hypothesis at the 10% significance level (assume the variances are not equal): The average �30-Year ROI� for Business majors is less than for Engineering Majors. Be sure to interpret your results.
