Among the 1104 males surveyed, 343 indicated they buy name-brand over-the-counter drugs; among the 1172 females surveyed, 295 indicated they buy name-brand over-the-counter drugs. Does the evidence suggest a lower proportion of females buy name-brand over-the-counter drugs? (a) Explain why this study can be analyzed using the methods for conducting a hypothesis test regarding two independent proportions. pilog ineven (b) What are the null and alternative hypotheses? (c) Describe the sampling distribution of Pfemale - Pmale. Draw a normal model with the area representing the P-value shaded for this hypothesis test. (d) Determine the P-value based on the model from part (c). (e) Interpret the P-value. (f) Based on the P-value, what does the sample evidence suggest? That is, what is the conclusion of the hypothesis test? Assume an a = 0.05 level of significance
