Find the mean. b. Find the standard deviation. c. Find the median. d. Construct a dotplot. e. Find the first quartile. f. Find the third quartile. g. Find the interquartile range. h. Construct a boxplot. i. Which of the points, if any, are outliers? j. If a histogram were constructed, would it be skewed to the left, skewed to the right, or approx- imately symmetric?
