Based on the sample evidence below, we want to test the hypothesis that population A has a larger variance than population B.

Sample A N=11, s^{2 =12.1,}

Sample B N=10, s^{2 =5}

Thep-value is approximately

Select one:

a..025.

b..05.

c..01.

d..10.

The test statistic for this problem equals

Select one:

a.1.1.

b.2.

c..4132.

d.2.42.

2The critical value ofFusing= .05when there is a sample size of 21 for the sample with the smaller variance, and there is a sample size of 9 for the sample with the larger sample variance is

Select one:

a.2.94.

b.2.37.

c.2.10.

d.2.45.
