Consider the data set : S = ( 67, 55, 64, 75, 81, 64, 62, 81, 73, 72, 54, 43, 70, 7, 39, 23, 33, 15, 67, 55, 89, 72, 47, 78 ) A- Construct a Stem-and-Leaf plot of the data by considering the 10's digits as stems and 1's digits as leaves. 3- Based on the stem-and-leaf plot in part A, is the distribution of the data right- kewed, left-skewed, or symmetric? - Find the mean and the median of the data. Do the mean and median support our findings in part B about the skewness of the data? Why
