Test whether the two variance are equal at 5% level of significance:

For the samples summarized below, test the hypothesis at ∞ =.05 that the two variances are equal. Variance Number of data values Sample 1 19 8 Sample 2 9 18

a. Reject the hypothesis because the test value 2.11 is less than the critical value 3.16.

b. Reject the hypothesis because the test value 4.46 is greater than the critical value 3.01.

c. Do not reject the hypothesis because the test value 2.11 is less than the critical value 3.16.

d. Do not reject the hypothesis because the critical value 3.01 is greater than the test value 4.46.
