Six independent samples of 100 values each are randomly drawn from populations that are normally distrubuted with equal variances. You wish to test the claim that If you test the individual claims that how many such tests are there? Assume that tests of equality between any two of the means are independent and that there is a .99 probility of not making a type I error on any one test. If all pairs of means are tested, what is the probability of making no type I errors?
