Which of the following statements are true with respect to a hypothesis test regarding the equality of the variances of two normally distributed populations? I). The F-statistic is the appropriate test statistic that should be used in this case. II). The chi-squared is the appropriate test statistic that should be used in this case. III). If the calculated statistic is within the critical values, than the conclusion would be not to reject the statement that the variances of the two populations are equal. IV). If the calculated statistic is within the critical values, than the conclusion would be to reject the statement that the variances of the two populations are equal.
Correct Answer: B
When testing for the equality of the variances of two normally distributed populations, the F-statistic is the appropriate test statistic. Furthermore, if the calculated F-statistic is within the critical F-values (in other words, the sample results are within the acceptance range), then the conclusion would be not to reject (or accept) the null hypotheses stating that the variances of the two populations are equal.
