A group in favor of freezing production of nuclear weapons believes that the proportion of individuals in favor of a nuclear freeze is greater for those who have seen the movie "The Day After" (population 1) than those who have not (population 2). In an attempt to verify this belief, random samples of size 500 are obtained from the populations of interest. Among those who had seen "The Day After", 228 were in favor of a freeze. For those who had not seen the movie, 196 favored a freeze. Which test should be used? OAZ test for proportions B. T test for proportions OCZ test for the difference between two proportions ODT test for the difference between two proportions QUESTION 20 While testing the null and alternate hypothesis: HO: p0.5 vs. Hap<0.5 p-value 0.0257 alpha 0.05 What is the correct decision? A none of these B. Reject HO OC Reject Ha D.Do not reject HO
