A magazine provided results from a poll of 2000 adults who were asked to identify their favorite pie. Among the 2000 ​respondents, 13​% 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 95​%, what is the value of α​?

If n=15, (x-bar)=37, and s=8, find the margin of error at a 80% confidence level Give your answer to two decimal places.

You want to get a 90% confidence interval for the difference between the percentage of females with red hair compared to males with red hair. You sample 76 females and find 34 of them have red hair. You sample 65 males and find 33 have red hair. < p1−p2 <

If n = 550 and X = 440, construct a 90% confidence interval for the population proportion, p. Give your answers to three decimals < p <

A magazine provided results from a poll of 1500 adults who were asked to identify their favorite pie. Among the 1500 respondents, 11% chose chocolate pie, and the A A margin of error was given as +4 percentage points. What values do p, q, n, E, and p represent? If the confidence level is 99%, what is the value of a? р, The value of p is the sample proportion. The value of q is found from evaluating 1- p. The value ofn 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.)
