Nuclear Weapons Freeze Narrative
A group in favour of freezing production of nuclear weapons believes that the proportion of individuals in favour 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 favour of a freeze. For those who had not seen the movie, 196 favoured a freeze.
-Refer to Environment Canada Project Narrative. Set up the appropriate rejection region for $\alpha$ = 0.01.
