The response rate is usually quite low. Suppose a company wants to test the response to a new flyer and sends it to 1050 people randomly selected from their mailing list of over 200,000 people. They get orders from 134 of the recipients. Use this information to complete parts a through d. a) Create a 90% confidence interval for the percentage of people the company contacts who may buy something. enter your response here%,enter your response here% (Round to one decimal place as needed.) Part 2 b) Explain what this interval means. A. The company is 90% confident that the probability a randomly sampled person will respond to the flyer falls within the confidence interval bounds. B.
