Assume that the amount of time people can hold their breath is normally distributed with a mean of 38 seconds and a standard deviation of 8 seconds. Take the time you held your breath (in Module 2) as the "raw score" and calculate the z-score of your time.
1. First try - 69 seconds
2. Second try - 74 seconds
3. Third try - 52 seconds

Look at your height, either on your Driver's License or ID card, or actually measured. Calculate the z-score of your height, based on the mean and standard deviation of the heights of people your gender.
1. My height is 5’10

Take your z-score from question 2, and calculate the height of a person of the opposite gender, if they had your same z-score (NOT your same height).
1. The height is 5’1

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
