Question
Two statistics teachers both believe that each has the smarter class. To put this to the test, they give the same final exam to their
students. A summary of the class sizes, class means, and standard deviations is given below:
=
n1
=
59,
=
182.9, $1
=
15.9
n2 54, 22 80.3, 82 18.9
Is there evidence, at an a 0.05 level of significance, to conclude that there is a difference in the two classes? Carry out an
appropriate hypothesis test, filling in the information requested.
A. The value of the standardized test statistic:
B. The p-value is
C. Your decision for the hypothesis test:
OA. Reject Ho-
B. Do Not Reject H1-
OC. Do Not Reject Ho.
OD. Reject H₁.
