Height of 10-Year-Old Males The heights of 10-year-old males are normally distributed with mean = 55.9 inches and o = 5.7 inches. (a) Draw a normal curve with the parameters labeled. (6) Shade the region that represents the proportion of 10-year-old males who are less than 46.5 inches tall. (C) Suppose that the area under the normal curve to the left of x = 46.5 is 0.0496. Provide two interpretations of this result
