2. Construct an ordered stem-and-leaf plot for the data given above in #8. Then, describe the shape of the distribution of the data set (either skewed left or skewed right or symmetric).
(HINT: to keep appropriate spacing, choose Times New Roman font format for cells used to display the plot and begin each entry with an apostrophe to make the values act as text versus a single number.)
