A magazine provided results from a poll of 2000 adults who were asked to identify their favorite pie. Among the 2000 respondents, 11% chose chocolate pie, and the margin of error was given as +5 percentage points. What values do p, q, n, E, and p represent? If the confidence level is 99%, what is the value of a? The value of p is the sample proportion. The value of q is found from evaluating 1 - p. The value of n is the sample size. The value of E is the margin of error. The value of p is the population proportion. If the confidence level is 99%, what is the value of a? α (Type an integer or a decimal. Do not round.)

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.
