Quick Self-Quiz: Five Number Summary and Skewness 1. Heights, revisited. A histogram of heights of 355 students is shown on the reverse. Use this graph to give a rough estimate of the five number summary of the heights in this sample. 2. For each five number summary below, indicate whether the data appear to be symmetric, skewed to the right, or skewed to the left. a). (10, 57, 85, 88, 93) b). (200, 300, 400, 500, 600) c). (5, 30, 40, 50, 75) d). (5, 7, 8, 15, 42) e). (100, 430, 600, 620, 650) Quick Self-Quiz: Estimating Mean and Standard Deviation The histogram below shows the data for the quantitative variable Height for 355 students. a). Estimate the mean and the standard deviation from the histogram. b). Estimate the value of the maximum height for a person in the sample and use your estimated values of mean and standard deviation to find and interpret an estimated z-score for this person's height. 20- Height
