Advertisements targeted to different groups should take such differences into account, if they exist. The researcher examines the most recent sales information of a particular car that comes in three colors.

Choose the competing hypotheses to determine whether color preference depends on the automobile buyer’s sex. H0: Color preference is independent of the automobile buyer’s sex.; HA: Color preference is dependent on the automobile buyer’s sex. H0: Color preference is dependent on the automobile buyer’s sex; HA: Color preference is independent of the automobile buyer’s sex. b-1. Calculate the value of the test statistic.

A research study investigated differences between male and female students. Based on the study results, we can assume the population mean and standard deviation for the GPA of male students are µ = 3.5 and σ = 0.6. Suppose a random sample of 100 male students is selected and the GPA for each student is calculated. What is the probability that the random sample of 100 male students has a mean GPA greater than 3.42?
