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.

What does the Empirical Rule state about the distribution of data within standard deviations of the mean?

How can you determine if a data set can be modeled with a normal distribution?

What is the significance of the area under the normal curve in relation to population percentages?

What percentage of 16-year-old girls are expected to be between 62 and 68 inches tall?

Explain how the normal distribution is symmetric and what that implies about the data.

Describe the process of calculating the percentage of girls taller than a specific height using the Empirical Rule.

How can the Empirical Rule be used to predict the height of 84% of 16-year-old girls?
