The cholesterol levels of a sample of children between the ages of 4 and 19 years of age were measured in mg/dl. the relative-frequency histogram for the data is shown to the right. state whether the distribution is (roughly) symmetric, right skewed, or left skewed. 190 200 210 220 230 0 0.1 0.2 0.3 0.4 cholesterol level (mg/dl) rel. frequency a histogram has a horizontal axis labeled "cholesterol level in milligrams per deciliter" from 190 to 230 in increments of 5 and a vertical axis labeled relative frequency from 0 to 0.4 in increments of 0.1. the histogram has vertical bars of width 5 starting at the horizontal axis value 195. the approximate heights of the bars are as follows, where the left horizontal axis label is listed first and the approximate height is listed second: 195, 0.04; 200, 0.15; 205, 0.21; 210, 0.32; 215, 0.18; 220, 0.04. which of the following best describes the given distribution? a. the distribution is right skewed. b. the distribution is nearly symmetric. c. the distribution is left skewed.
