Use the Information in Example 6.3 to answer the following questions. a. Suppose a 15 to 18-year-old male from Chile was 176 cm tall from 2009 to 2010. The z-score when x 176 cm is z = _______. This z-score tells you that x = 176 cm Is ________ standard deviations to the ________ (right or left) of the mean ______ (What Is the mean?). b. Suppose that the height of a 15 to 18-year-old male from Chile from 2009 to 2010 has a z-score of z —2. What is the male’s height? The z-score (z = —2) tells you that the male’s height is _________ standard deviations to the (tight or left) of the mean.

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.
