22. The side-by-side boxplots below display the distribution of two data sets A and B. Set A Set B Read the following three statements which are intended to compare these two data sets: (I) Data set A contains more data than data set B. (II) The mean of data set B is greater than the mean of data set A. (III) The data in set A has larger range than the data in set B. ~ Which of the above three statements is/are best supported by these boxplots? (a) Only statement (1) is true. ) Only statement (II) is true. (c) Only statement (III) is true. (d) Only statements (1) and (III) are true. Only statements (II) and (III) are true.16. In 14. One small tutorial had only n = 15 students. These are the grades for one particular worksheet in that tutorial: (6, 8, 6, 8, 7, 6, 6, 8, 7, 8, 8, 7, 7, 6, 7) = 105 Calculate the standard deviation of these worksheet grades. Round your answer to three decimal places. 7 Hint: Note that these students only have three types of grades. Some of them got 6's, some 7's and others 8's. That should make your calculations quicker. 0.58 S 0.67 ( c ) 0.38 (d ) 0.85 (e) 0.82
