Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value f/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=163, x=29.3 hg, s= 7.7 hg. The confidence level is 95%. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. ¹/2= (Round to two decimal places as needed.) OB. Za/2 KIDS (Round to two decimal places as needed.) OC. Neither the normal distribution nor the t distribution applies.
