Breathing rates for humans can be as low as 4 breaths per minute or as high as 70 or 75 for a person doing strenuous exercise. Suppose that the resting breathing rates for college-age students have a distribution that is mound-shaped, with a mean of 14 and a standard deviation of 1.1 breaths per minute. What fraction of all students would have breathing rates in the following intervals? (a) 12.9 to 15.1 breaths per minute 0.34 (b) 11.8 to 16.2 breaths per minute 0.62 (c) more than 17.3 or less than 10.7 breaths per minute 1.03
