For this discussion board, you will find the confidence interval for the difference between to population proportions, similar to example 9.13 and 9.14 on page 545 in your textbook.

Initial Post:

First, you will need to find data (construct it yourself with context or link to a source) from two independent samples where the conditions on page 542 are met:

• All possible samples of a given size have an equal probability of being chosen.
• The samples are independent.
• The conditions for a binomial distribution are met.
• The sample size are large enough such that np > 5, and n(1 – p)  > 5 for both samples

Following examples 9.13, 9.14, construct a confidence interval for the difference of your two population proportions at c = 95%. 

You may attach a file with your raw data however, your answer (calculations, confidence interval) must be in the body of the post.

Response Post: You will create a different confidence interval for the difference of the proportions for the specific data of one (1) classmate, but using a different significance level than the original poster and those who responded before you. Is your interval larger or smaller than others? Explain.

Your answer (calculations, confidence interval) must be in the body of the post.
