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=218, x=28.6 hg, s=6.6 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=enter your response here (Round to two decimal places as needed.) B. zα/2=enter your response here (Round to two decimal places as needed.) C. Neither the normal distribution nor the t distribution applies.
