question 6

Multiple Choice

A random sample of size 25 from normal population A has a variance of 110.A random sample of size 5 from normal population B has a variance of 200.You will test the hypothesis that the variance of population A is equal to the variance of population B, using a 2% significance level.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.
