You want to know about the difference in the percentage of men whoget sick when exposed to H1N1 and the percentage of women who get sick when exposed toH1N1 after being treated with our drug. So, you give 150 men GRGSBZ1 and then expose them tothe virus. You find that 20 of them got sick with the virus. You do the same to 200 women andfind that only 15 got sick. Build a 95% confidence interval for p1-P2 where p, is the percentageof all men who would get sick in this situation and p2 is the corresponding percentage for thewomen.

Given data: For men: n1 = 150 x1 = 20 For Women: n2 = 200 x2 = 15 Confidence level = 95%…

Answered: You want to know about the difference…

A research poll of 1501 adults showed that 1051 of respondents believe in global warming. Find a 98% confidence interval estimate for the proportion of adults that believe in global warming.

If a 90% confidence interval for the difference of proportions contains some positive and some negative values, what can we conclude about the relationship between p1 and p2 at the 90% confidence level? There is a positive difference between p1 and p2. There is no difference between p1 and p2. There is a negative difference between p1 and p2. We cannot make a conclusion about the relationship between p1 and p2.
