You are testing the claim that the mean GPA of night students is different from the mean GPA of daystudents. You sample 35 night students, and the sample mean GPA is 2.68 with a standard deviation of0.36. You sample 30 day students, and the sample mean GPA is 2.59 with a standard deviation of 0.75. Testthe claim using a 1% level of significance. Assume the population standard deviations are unequal and thatGPAS are normally distributed. Give answer to at least 4 decimal places.What are the correct hypotheses?Ho: μ₁H₁: U₁Based on the hypotheses, find the following:Test Statistic =p-value =H₂H₂The correct decision is to Reject the null hypothesisThe correct summary would be: There is enough evidence to support the claimnight students is different from the mean GPA of day students.that the mean GPA of
