Question

A college physics professor thinks that two of her sections scored differently on the final exam.

She collects the scores for the two classes and stores them in a file.

We do not know anything about the test score distributions.

Answer the following. Use alpha = 0.05.

a). What is the value of the test statistic?

b). What is the p-value?

c). Is she correct in stating that the final exam scores from the two sections are not equal to each other?

Here is the data...

74   75
79   77
65   76
58   82
67   88
61   91
63   92
64   70
62   89
72   85
66   71
58   82
66   91
63   77
61   67
73   87
77   92
68   88
62   94
67   85
81   97
80   93
58   74

Answer 1

From the given data

(1) Null and Alternative Hypothesis:

H0: There is no significance difference between the final exam scores of two sections
H1: There is significance difference between the final exam scores of two sections

Let the los be alpha = 5%

Thus we conclude that there is significance difference between the final exam scores of two sections
