B. Identify the test statistic Z=___ C. Identify the P-value. P-value=___ D. What is the conclusion based on the hypothesis test? The P-value is (greater than/less than) the significance level of α=0.01,so (reject/ fail to reject) the null hypothesis. There is (suffiecient/ insufficient) evidence to support the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25. Test the claim by constructing an appropriate confidence interval. The 90% confidence interval is ___<( p1-p2)<___ E. Because the confidence interval limits (do not include/include) 0, it appears that the two proportions are (equal/not equal) Because the confidence interval limits include (only negative/ only positive/ negative and positive) values, it appears that the proportion of people over 55 who dream in black and white is (greater than/less than/ not significantly different from) the proportion for those under 25.
