Extracted text: Use the accompanying data set on the pulse rates (in beats per minute) of males to complete parts (a) and (b) below. E Click the icon to view the pulse rates of males. 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 beats per minute. (Round to one decimal place as needed.) The standard deviation of the pulse rates is beats per minute. (Round to one decimal place as needed.) Explain why the pulse rates have a distribution that is roughly normal. Choose the correct answer below. O A. The pulse rates have a distribution that is normal because a histogram of the data set is bell-shaped and symmetric. O B. The pulse rates have a distribution that is normal because none of the data points are greater than 2 standard deviations from the mean. O C. The pulse rates have a distribution that is normal because none of the data points are negative. O D. 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. b. Treating the unrounded values of the mean and standard deviation as parameters, and assuming that male pulse rates are normally distributed, find the pulse rate separating the lowest 2.5% and the pulse rate separating the highest 2.5%. These values could be helpful when physicians try to determine whether pulse rates are significantly low or significantly high. The pulse rate separating the lowest 2.5% is (Round to one decimal place as needed.) beats per minute. The pulse rate separating the highest 2.5% is beats per minute. (Round to one decimal place as needed.)
