The sample size needed to estimate the difference between two population proportions to within a margin of error m with a significance level of α can be found as follows. In the expression m=z∗p1(1−p1)n1+p2(1−p2)n2−−−−−−−−−−−−−−−−−−−−√ we replace both n1 and n2 by n (assuming that both samples have the same size) and replace each of p1, and p2, by 0.5 (because their values are not known). Then we solve for n, and get n=(z∗)22E2. Finally, increase the value of n to...

4 Chapter 7 Test B 16. [Objective: Calculate and interpret confidence intervals for a proportion) A random sample of 950 adult television viewers showed that 48% planned to watch sporting event X. The margin of error is 4 percentage points with a 95% confidence level. Does the confidence interval support the claim that the majority of adult television viewers plan to watch sporting event X? No; the confidence interval means that we are 95% confident that the population proportion of...
