Statistics students were asked to fill one-cup measuring cups from boxes of Kellogg's Raisin Bran cereal, and then to count the number of raisins in the one-cup serving. The results, from 13 students, were sampled and are shown here. 23, 33, 44, 36, 29, 42, 31, 33, 61, 36, 34, 23, 24. So (23-two, 24-one, 29-one, 31-one, 33-two, 34-one, 36-two, 42-one, 44-one, 61-one) Calculate the following summary statistics: average, mode, median, standard deviation, range, and coefficient of variation. What are the 25th , 50th and 75th percentiles?
