You are testing the claim that the mean GPA of night students is different from the mean GPA of day students. A sample of 26 night students and 21 day students and their GPA's are recorded below. Test the claim using a 10% level of significance. Assume the population variances are unequal and that GPAs are normally distributed. Give answers to 4 decimal places.
