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.

Braking Reaction Times: Histogram Listed below are sorted braking reaction times (in 1/10,000 sec) for male and female subjects (based on data from the RT-2S Brake Reaction Time Tester). Construct a histogram for the reaction times of males. Use a class width of 8 and use 28 as the lower limit of the first class. For the horizontal axis, use class midpoint values. Does it appear that the data are from a population with a normal distribution?
