Roll two dice and add the numbers. Roll the dice 20 times and record your results. Compute the mean, median, and mode for your data set. Now, replace one of your results with 100. Calculate the mean, median, and mode for this new data set. How did these change?
According to the National Center for Health Statistics, the mean height of an American male is 69.3 inches and the mean height of an American female is 63.8 inches. The standard deviation for both genders is 2.7 inches. Assume height is approximately normal for each gender. Calculate your z-score within your gender. Find your percentile using Table 6.3 on page 396 of your text. What percent of your gender is shorter than you are? What percent is taller than you?
