Question: 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 2009.
At the 5% significance level, can you conclude that the mean time taken to find their first full-time job for all May 2009 graduates in these fields is the same?
