A magazine provided results from a poll of 1000 adults who were asked to identify their favorite pie. Among the 1000 respondents, 11% chose chocolate pie, and the margin of error was given as ±5 percentage points. Describe what is meant by thestatement that "the margin of error was given as ±5 percentage points."Choose the correct answer below.A. The statement indicates that the true population percentage of people that prefer chocolate pie is in the interval 11% ± 5%.B. The statement indicates that the study is only 5% confident that the true population percentage of people that prefer chocolate pie is exactly 11%.C. The statement indicates that the study is 100% - 5% = 95% confident that the true population percentage of people that prefer chocolate pie is 11%.D. The statement indicates that the interval 11% ± 5% is likely to contain the true population percentage of people that prefer chocolate pie.
