11.3 Semester GPAs are compared for seven randomly chosen students in each class level at Oxnard University. Does the data prove a significant difference in mean GPAs?

Please see the attachment and interpret the results.

If we are doing a test using a significance level of 5% and we get a p value of less than that- what does that mean?
