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 2.35 with a standard deviation of 0.46. you sample 25 day students, and the sample mean gpa is 2.58 with a standard deviation of 0.47. test the claim using a 5% level of significance. assume the sample standard deviations are unequal and that gpas are normally distributed. give answer to exactly 4 decimal places.

Will give the box plots below show the math scores of students in two different classes: class a 55 72 75 89 95 class b 55 70 75 94 100 based on the box plots, which statement is correct? a: the median score of class a is greater than the median score of class b. b: the lower quartile of class a is greater than the lower quartile of class b. c: the upper quartile of class a is greater than the upper quartile of class b. d: the maximum score of class a is greater than the maximum score of class b.
