The distribution of red blood cell counts is different for men and women in a certain population. For both, the distribution is approximately Normal. For men, the middle 95% range from 4.7 to 5.8 million cells per microliter, and for women, the middle 95% have red blood cell counts between 3.7 and 4.6 million cells per microliter. Complete parts (a) through (c) below. a. What is the mean and the standard deviation of red blood cell counts for the men? Explain your reasoning. Find the mean for the men. Explain your reasoning. Select the correct choice below and fill in the answer box to complete your choice. (Round to two decimal places as needed.) 0 A- The mean is D million. Since the mode of the Normal distribution is equal to its mean, the mean is the higher of the boundary values for the middle 95%. O B- The mean is D million. Since the Normal distribution is symmetric about its mean, the mean is the lower of the boundary values for the middle 95%. O C- The mean is D million. Since the mode of the Normal distribution is equal to its mean, the mean is equal to the distance between the boundary values for the middle 95%. O D- The mean is D million. Since the Normal distribution is symmetric about its mean, the mean is right in the middle, which is the average of the boundary values for the middle 95%
