question 86

Multiple Choice

A random sample of size 15 selected from normal population A has standard deviation of 80.A second, independent, random sample of size 8 selected from normal population B has a standard deviation of 100.You will test a null hypothesis that the variances of the two populations are equal, 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.
