You are testing the claim that the mean GPA of night students is different from the mean GPA of day students. You sample 30 night students, and the sample mean GPA is 2.34 with a standard deviation of 0.55. You sample 35 day students, and the sample mean GPA is 1.99 with a standard deviation of 0.68. Test the claim using a 5% level of significance. Assume the population standard deviations are unequal and that GPAS are normally distributed. Give answer to at least 4 decimal places. Do not pool variances. What are the correct hypotheses? Họ: Select an answer Select an answer H1: Select an answer ? v Select an answer Based on the hypotheses, find the following: Test Statistic = Critical Values = ± (Just enter the positive CV.) The correct decision is to Select an answer The correct summary would be: Select an answer mean GPA of night students is different from the mean GPA of day students. that the
