Question

A high school principal claims that the variance in GPA of students in the graduating class is less than 0.49.
You test this claim by sampling 33 seniors and find their GPA's to have a variance of 0.37.
Ho:o = 0.49
Ha:o < 0.49 (Claim)
Is there enough evidence to reject Ho and support the principal's claim at a 0.05 level of significance?
Yes, because the test statistic x
20.072 is in the rejection region with critical value 24.163.
O No, because the test statistic y
20.072.
24.163 is NOT in the rejection region with critical value
%3D
O No, because the test statistic y
20.072 is NOT in the rejection region with critical value
20.867.
O No, because the test statistic Y
20.072.
= 20.867 is NOT in the rejection region with critical value
Yes, because the test statistic y = 24.163 is in the rejection region with critical value 20.072.
