In clinical studies of the allergy drug Seldane, 70 of the 785 subjects experienced drowsiness (based on data from Merrell Dow Pharmaceuticals, Inc.). A competitor claims that 7% of Seldane users experience drowsiness. Use a 0.10 significance level to test if the claim is true.  Write down the null and alternative hypotheses. Check the necessary conditions for carrying out the hypothesis testing. Compute the observed test statistic. Find the corresponding P-value. Based on the P-value in (d) and α = 0.10, what are the decision and final conclusion? 4

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
