A right-tailed test for the ratio of two population variances Η₀: / ≤ 1 examines whether is greater than .

Question

Quizplus · Accepted Answer

The null hypothesis for a right-tailed test of the ratio of two population variances is that the ratio is less than or equal to 1. Therefore, if the alternative hypothesis is that the ratio is greater than 1, then the test is a right-tailed test. This means that the p-value will represent the probability that the ratio is greater than the null value of 1. So, if the p-value is less than the chosen significance level, we would reject the null hypothesis and conclude that the ratio is significantly greater than 1.
