A half-century ago, the mean height of women in a particular country in their 20s was 62.1 inches. Assume that the heights of today's women in their 20s are approximately normally distributed with a standard deviation of 2.85 inches. If the mean height today is the same as that of a half-century ago, what percentage of all samples of 24 of today's women in their 20s have mean heights of at least 63.42 inches? About nothing% of all samples have mean heights of at least 63.42 inches.
