1. When we decide to reject the null hypothesis, the probability of committing a Type l error will not be smaller than the computed p-value. True or False? 2. Suppose two kinds of thread are being compared for strength. If fifty pieces of each type of thread are tested under similar conditions, then a paired sampling approach should be used. True or False? 3. In a two-tailed test of hypothesis, if the null hypothesis is rejected at a = 0.01 level of significance, then the probability of committing a type Il error is always 0. True or False? 4. The variances of two populations can be compared so long as the two random samples are normally distributed. True or False?
