Question 8

A magazine provided results from a poll of 1000 adults who were asked to identify their favorite pie. Among the 1000 respondents, 13% chose chocolate pie, and the margin of error was given as 15 percentage points. What values do p, q. n, E, and p represent? If the confidence level is 90%, 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 90%, what is the value of a? a= 0.10 (Type an integer or a decimal. Do not round.)
