Points: U of 1 sdve Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value to /2. (b) find the critical value zo / 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 = 191, x = 32.4 hg. s = 7.3 hg. The confidence level is 99%. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. tax/2 = 1.98 (Round to two decimal places as needed.) OB. Zu/ 2 = (Round to two decimal places as needed.) O C. Neither the normal distribution nor the t distribution applies
