I am looking for assistance in calculating the effect size for this problem using T-Tests.

A researcher wishes to learn whether the GPA of incoming flight students may be a factor in the number of flight hours the student completes in the first semester of college. The researcher has collected the flight hours of a random sample of students in a group of high GPA students and low GPA students.

Low GPA                           High GPA

42                                             43                                         

45                                             51

40                                             56         

37                                             40

41                                             32

41                                             54

48                                             51   

50                                             55

45                                             50

46                                             48       

The researcher is testing whether GPA may be a factor in differences in flight time accumulated in the first semester at college. Their hypothesis is: The mean flight time of students with a low GPA is different than those incoming students with a high GPA. A t-test can be used to test the probability that the two means do not differ. The alternative is that the means differ; one of them is greater than the other. This is a two-tailed test because the researcher is interested in if GPA changes flight time.
