D Question 5 2 pts During a semester, I taught one class of statistics and two classes of precalculus. 18 out of 35 students in statistics are male, and 34 out of 57 students in precalculus are male. Suppose each of these sample proportions are random samples taken from the population of all WCU students that are taking statistics or precalculus. Let ps represent the sample proportion of male students taking statistics and po represent the sample proportion of male students taking precalculus. Is there convincing evidence to suggest that the proportion of all WCU students taking statistics that are male differs from the proportion of all WCU students taking precalculus that are male? Calculate a test statistic for a two proportion z-test. Give your answer as a decimal rounded to 2 places after the decimal
