a. Conduct all parts of a significance test to analyze whether the population means differ for females and males. Interpret the P-value, and report the conclusion for α-level = 0.05. b. If you were to construct a 95% confidence interval comparing the means, would it contain 0? Answer based on the result of (a), without finding the interval.
