Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value t12. (b) find the critical value z.12, 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=265, x= 32.7 hg, s= 6.3 hg. The confidence level is 90%. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. ta/2= (Round to two decimal places as needed.) O B. Za/2= (Round to two decimal places as needed.) O C. Neither the normal distribution nor the t distribution applies.
