Use the accompanying data set on the pulse rates (in beats per minute) of males to complete parts (a) and (b) below. LOADING... Click the icon to view the pulse rates of males. Question content area bottom Part 1 a. Find the mean and standard deviation, and verify that the pulse rates have a distribution that is roughly normal. The mean of the pulse rates is 71.771.7 beats per minute. (Round to one decimal place as needed.) Part 2 The standard deviation of the pulse rates is 12.112.1 beats per minute. (Round to one decimal place as needed.) Part 3 Explain why the pulse rates have a distribution that is roughly normal. Choose the correct answer below. A. The pulse rates have a distribution that is normal because none of the data points are greater than 2 standard deviations from the mean. B. The pulse rates have a distribution that is normal because a histogram of the data set is bell-shaped and symmetric. Your answer is correct.C. The pulse rates have a distribution that is normal because the mean of the data set is equal to the median of the data set. D. The pulse rates have a distribution that
