Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value t,,/2, (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= 190, x= 28.5 hg, s= 6.3 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. tu/2 =
(Round to two decimal places as needed.)
OB.
Za/2 =
(Round to two decimal places as needed.)
O C. Neither the normal distribution nor the t distribution applies.
