Test the claim that for the population of female college students, the mean weight is given by mu equals 132 space l b s. Sample data are summarized as n = 20, x̅ = 137 lb, and s = 14.2 lb. Use a significance level of α = 0.1. Assume that a simple random sample has been selected from a normally distributed population. Find the test statistic.

t-stat = 1.57

z-stat = 1.03

z-stat = 2.42

t-stat = 1.03
