Direct mail advisors send notifications to thousands of potential customers in the hope that summer by the company's product. The response rate is usually quite low. Suppose a company wants to test the response to a new flyer and send it to 1060 people randomly selected from their mailing list of over 200,000 people. They get orders from 110 of those people. A) Create a confidence interval for the percentage of people to company contracts who may buy something

Create a 90% confidence interval for the percentage of people the company contacts who may buy something.Answer:CI = (8.84%, 11.92%)We are 90% Confident that the percentage of people the company contacts who may buy something is between 8.84% and 11.92%.Step-by-step explanation:We are given;n = 1060x = 110Confidence level = 90%Sample proportion; p^ = x/n = 110/1060p^ = 0.1038DF = n - 1 = 1060 - 1 = 1059From the table attached, the critical value for a confidence level of 90% at a DF greater than 1000 is 1.645Formula for CI is;CI = p^ ± t√(p^(1 - p^)/n)CI = 0.1038 ± 1.645√(0.1038(1 - 0.1038)/1060)CI = 0.1038 ± 0.0154CI = (0.0884, 0.1192) orCI = (8.84%, 11.92%)Thus, we are 90% Confident that the percentage of people the company contacts who may buy something is between 8.84% and 11.92%.
