4. A 2012 Gallup poll surveyed Americans about their employment status and whether or not they have diabetes. The survey results indicated that 717 of the 47,774 employed (full or part time) and 146 of the 5,855 unemployed 18-29 year olds have diabetes. (a) If you suspect that that having diabetes and being unemployed might be related somehow, then what is the null and alternative hypothesis?

(b) What is the pooled proportion?

(c) What is the standard error? (SE)

(d) What is the Z-score?

(e) What is the p-value?

(f) What is the decision?

(g) What is the conclusion?

(h) In this context, what does the p-value represent?

A recent Gallup poll asked 1006 Americans, “During the past year, about how many books, either hardcover or paperback, did you read all or part of the way through?” Results of the survey indicated that x ¯ = 13.4 books and s = 16.6 books. Construct a 99% confidence interval for the true mean number of books Americans read either all or part of during the past year.

2. According to a Gallup poll conducted in 2008, 78.3% of Americans felt satisfied with the way things were going in their personal lives. A researcher wonders of the percentage satisfied is lower today. To find out, the researcher surveys a random sample of 1,173 Americans, and finds that 895 feel satisfied with the way things are going in their personal lives. The researcher wishes to test the null hypothesis at a significance level of 0.05. (a) Conduct a large...

A Gallup poll to survey the top concerns of Americans was conducted. Suppose that 387 women and 359 men were independently and randomly selected, and that 242 women and 202 men chose the state of the economy as their biggest concern. Can we conclude that the proportion of women (p1), choosing the state of the economy as their biggest concern, exceeds the proportion of men (p2)?  Use a significance level of α=0.01 for the test. Step 1: Choose the correct alternative...
