Analysis Variance

Semester GPSs were collected for seven randomly chosen students in four majors at Oxnard University

Solution

The test hypothesis:

Ho: there is no difference in the mean GPA for the four majors. (i.e. null hypothesis)

Ha: there is a difference in the mean GPA for the four majors. (i.e. alternative hypothesis)

The test statistic is

F=3.52

The p-value of F test is 0.0304 (from F test)

Since the p-value is less than 0.05, we reject the null hypothesis.

So we can conclude that there is a difference in the mean GPA for the four majors.
