***For each of the three confidence intervals you construct, include a sentence that interprets the confidence interval (even though the question in the book does not specify to do so).

***Be sure to answer the question in a paragraph about what happens to interval-width when you increase sample size

For each of the following three sample sizes, construct the 95% confidence interval for the population proportion. Use a sample proportion of 0.40 throughout. What happens to interval width as sample size increases? Why?

Ps = 0.40

Sample A: N=100

Sample B: N=1000

Sample C: N=10,000
