A university employment office wants to compare the time taken by graduates with three different majors to find their first full-time job after graduation. The following table lists the time (in days) taken to find their first full-time job after graduation for a random sample of eight business majors, seven computer science majors, and six engineering majors who graduated in May 2019 a. Suppose you must test the hypothesis at 5% level of significance whether the mean time taken to find their first full-time job for all May 2019 graduates in these fields is the same. What is your conclusion? b. Suppose you reject the null hypothesis, use the LSD method to compare the difference in the meantime taken to find their first full-time job for Business and Computer Science graduates using 95% confidence interval.

A university employment office wants to compare the time taken by graduates with three different majors to find their first full-time job after graduation. The following table lists the time (in days) taken to find their first full-time job after graduation for a random sample of eight business majors, seven computer science majors, and six engineering majors who graduated in May 2019
a. Suppose you must test the hypothesis at 5% level of significance whether the mean time taken to find their first full-time job for all May 2019 graduates in these fields is the same. What is your conclusion?
b. Suppose you reject the null hypothesis, use the LSD method to compare the difference in the meantime taken to find their first full-time job for Business and Computer Science graduates using 95% confidence interval.
