Predicting Intervals and Population Percentages Using the Empirical Rule

This video tutorial explains how to use the Empirical Rule to predict intervals and population percentages in normally distributed data. It covers the characteristics of normal distributions, such as the bell curve shape and the relationship between the mean and standard deviation. The tutorial applies these concepts to the heights of 16-year-old girls, providing a detailed breakdown of height intervals. It also explores different strategies for calculating percentages and highlights multiple approaches to solving related problems.
