Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value t,12, (b) find the critical value z,r12, 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 = 195, x= 28.4 hg, s= 7.6 hg. The confidence level is 95%. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. ta/2 = (Round to two decimal places as needed.) %3D B. Za/2 = (Round to two decimal places as needed.) %3D C. Neither the normal distribution nor the t distribution applies.
