Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value tα/2, (b) find the critical value zα/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=165,xˉ=32.7 hg, s=7.5 hg. The confidence level is 99%. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. tα/2= (Round to two decimal places as needed.) B. Zα/2= (Round to two decimal places as needed.) C. Neither the normal distribution nor the t distribution applies.
