Data set 2 (a). For this series of questions you will perform an F ratio variance test on the following two samples:

Set A: 7, 9, 9, 11, 11, 13

Set B: 5, 5, 8, 10

You will be asked to provide:

(a, 4 pts) The value of F.

(b, 3 pts) The appropriate critical F value corresponding to an overall alpha value of 0.05 for the F test.

(c, 3 pts) Indicate whether the test suggests that the population variances are not significantly different, the variance of set A appears significantly smaller than data set B, or the variance of set A appears significantly larger than data set B.

PART C OPTIONS:

The population variances are not significantly different
	The variance of set A appears significantly smaller than data set B
	The variance of set A appears significantly larger than data set B
