Week 6 Project Assignment

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

Using the ROI data set:

  • 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.
  • 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.

Please provide original work. No plagarizing.
