A half-century ago, the mean height of women in a particular country in their 20s was 62.8 inches. Assume that the heights of today's women in their 20s are approximately normally distributed with a standard deviation of 2.31 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 64.11 inches? About 1% of all samples have mean heights of at least 64.11 inches. Round to one decimal place as needed.)
