D Question 4 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 pp 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? What is the hypothesis for a two proportion z-test. Hint: Test using Ps - Pp Edit View Insert Format Tools Table
