Business Statistics 

For these project assignments throughout the course you will need to reference the data in the ROI Excel spreadsheet. Download it here.

Using the ROI data set:

1. For each of the 2 majors test the hypothesis at the 5% significance level: 

o 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): 

o The average ’30-Year ROI’ for Business majors is less than for Engineering Majors.  Be sure to interpret your results.
