A magazine provided results from a poll of 2000 adults who were asked to identify their favorite pie. Among the 2000 respondents, 14% chose chocolate pie, and the margin of error was given as ±3 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? (Type an integer or a decimal. Do not round.)
