Assume that we want to construct a confidence interval. Do one of the following, as appropriate (a) find the critical value t2, (b) find the critical value z2, 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 = 222, x = 28 5 ng s=62 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. la/2= (Round to two decimal places as needed) B. Za/2 (Round to two decimal places as needed) C. Neither the normal distribution nor the t distribution applies.
