A Random Sample of Size 9 Is Selected from Normal

question 19

Multiple Choice

A random sample of size 9 is selected from normal population A.A second, independent, random sample of size 6 is selected from normal population B.You test a null hypothesis that the variances of the two populations are equal, using a 10% significance level.The F_stat for your test, calculated as the ratio of the variance of sample A to the variance to the variance of sample B, turns out to be 1.21.Report your conclusion.

• A)Since F_stat is greater than F_c, we cannot reject the "equal variances" null hypothesis.
• B)Since F_stat is less than F_c, we cannot reject the "equal variances" null hypothesis.
• C)Since F_stat is less than F_c, we can reject the "equal variances" null hypothesis.
• D)Since F_stat is greater than F_c, we can reject the "equal variances" null hypothesis.
