Here are summary statistics for randomly selected weights of newborn girls: $n = 36$, $ar{x} = 3180.6$ g, $s = 700.5$ g. Use a confidence level of 95% to complete parts (a) through (d) below. a. Identify the critical value $t_{alpha/2}$ used for finding the margin of error. $t_{alpha/2} = Box$ (Round to two decimal places as needed.)
