C) X-test
D) Y-test

Question

Quizplus · Accepted Answer

The F-test is commonly used to compare the variances of two samples. It calculates the ratio of the variances and determines whether the ratio is significantly different from 1. If the ratio is significantly greater than 1, it indicates that there is more variability in one sample compared to the other. Therefore, the F-test is the appropriate choice for this scenario. There is no such thing as X-test or Y-test, and the Z-test is used to compare means, not variances.
