You are testing the claim that the mean GPA of night students is different from the mean GPA of day students. You sample 60 night students, and the sample mean GPA is 2.16 with a standard deviation of 0.79. You sample 20 day students, and the sample mean GPA is 2.09 with a standard deviation of 0.93. 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. What are the correct hypotheses? Ho: H, Test Statistic = =H₂₁ H₁: ₁ Based on the hypotheses, find the following: Critical Values= ± o #v OF H₂ OF (Just enter the positive CV.) Or
