Question 1

True or false? The F-value F0.01 has area 0.99 to its left.
◦ True
◦ False

Question 2

A hypothesis test for two population standard deviations is to be performed. Independent random samples of sizes n1 and  n2 are drawn from the two populations. The variable under consideration is normally distributed on each of the two populations. The test statistic is  If the null hypothesis, is true, what is the distribution of this test statistic?
◦ F-distribution with df = (n2- 1, n1 - 1)
◦ F-distribution with df = (n1 - 1, n2- 1)
◦ χ2-distribution with df = n1 + n2 - 1
◦
F-distribution with df = (n1, n2)
