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)

These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
