Final answer:
The question involves understanding percentiles and the distribution of heights in a population, and it would typically require statistical information about the correlation between mothers' and daughters' heights to provide a precise answer.
Step-by-step explanation:
The question relates to the concept of percentiles in statistics, which is a part of Probability and Statistics. To determine the proportion of mothers on the 90th percentile of mothers' heights who have daughters taller than the 90th percentile of daughters' heights, we need additional data regarding the distribution of heights. We can use the provided statements to imply correlations and typical data distribution spreads, but we can't provide a definitive answer without specific data indicating the relationship between mothers' and daughters' heights.
The empirical rule, also known as the 68-95-99.7 rule, can help estimate the percentage of observations lying within a certain range of the mean for normal distributions. However, assessing the proportion of daughters taller than their mothers would likely require knowledge of the correlation coefficient between mothers' and daughters' heights as well as the corresponding regression line.
