Question
You are testing the claim that the mean GPA of night students is different from the mean GPA of day
students. You sample 35 night students, and the sample mean GPA is 2.68 with a standard deviation of
0.36. You sample 30 day students, and the sample mean GPA is 2.59 with a standard deviation of 0.75. Test
the claim using a 1% level of significance. Assume the population standard deviations are unequal and that
GPAS are normally distributed. Give answer to at least 4 decimal places.
