Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value ta/2 , (b) find the critical value za/2 , or (c) state that neither the normal distribution nor the t distribution applies. Here are summary statistics for randomly selected weights of newborn girls: n=162, x=30.9 hg, s=7.1 hg. The confidence level is99% I need to learn how to calculate the critical value Ta/2?
