Using the data attached, calculate the confidence interval, and the error bound: 1. How much area is in both tails(combined)? a=  2.How much area is in each tail? a/2 3. Some students think that a 90% confidence interval contains 90% of the data. Use the list of data attached and count how many data values lie within the confidence interval. What percent is this? Is this percent close to 90%? Explain why this percent should or should not be close to 90%?

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
