1.if your data is a random sample of size n from the distribution N(4, 7), then what is the distribution of the statistic X(not Z or T)? Z?T?
2.Suppose you are testing H0: N(55, 64) vs. H1 N(45, 49), with α = .05. Your test will be one draw x from one of these two populations. You standardize H0 to N(0, 1). What is H1?
