These next questions come after part B. Which of the statements correctly describes the relationship between the mean and median in the histogram of the number of servings of fruit per day claimed by the 7474 seventeen‑year‑old girls? A) The mean and median are about equal because the distribution is right‑skewed. B) The mean is larger than the median because the distribution is right‑skewed. C) The median is larger than the mean because the distribution is right‑skewed. D) There is not enough information to tell us about the relationship between the mean and median in the histogram. (c) In general, you cannot find the exact values of median, quartiles, or mean from the histogram. What is special about the histogram of the number of servings of fruit that allows you to do this? Select an answer choice. A) We know exactly how many observations fall in each bin because of the way the bins are constructed. B) The sample size only consists of only 74…
