Chi-Square and Analysis of Variance

Problem-50: Chi-Square and Analysis of Variance

From a sample of 25 observations, the estimate of the standard deviation of the population was found to be 15.0. From another sample of 14 observations, the estimate was found to be 9.7. Can we accept the hypothesis that the two samples come from populations with equal variances, or must we conclude that the variance of the second population is smaller? Use the 0.01 level of signifi cance.
