Census data for a certain county show that 19% of adult residents are Latin@s, Suppose 72 people are called for jury duty and only 9 of them are Latin@s. (Latin@ is shorthand for "Latina or Latino.") Does this apparent underrepresentation of Latin@ people call into question the fairness of the jury selection process, that is, is there evidence that the proportion of Latin@ people on the jury is less than we would expect if the selection process is fair? a. Write null and alternative hypotheses. b. Calculate the test statistic Z and the P-value. c. Does the data provide evidence that the process is unfair? Why?
