The following data show the median starting salary, the mid-career salary, and the percentage increase from starting salary to mid-career salary for the 20 college degrees with the hi ghest mid-career salary (America.EDU website). a. Using a class width of 10 , construct a histogram for the percentage increase in the starting salary. b. Comment on the shape of the distribution. c. Develop a stem-and-leaf display for the percentage increase in the starting salary. d. What are the primary advantages of the stem-and-leaf display as compared to the histogram? \begin{tabular}{|l|l|l|l|} \hline & A & B & C \\ \hline \( \mathbf{1} \) & Observation & x & \( y \) \\ \hline \( \mathbf{2} \) & 1 & \( \mathrm{~A} \) & 1 \\ \hline \( \mathbf{3} \) & 2 & \( \mathrm{~B} \) & 1 \\ \hline \( \mathbf{4} \) & 3 & \( \mathrm{~B} \) & 1 \\ \hline \( \mathbf{5} \) & \( \mathbf{4} \) & \( \mathrm{C} \) & 2 \\ \hline \( \mathbf{6} \) & 5 & \( \mathrm{~B} \) & 1 \\ \hline \( \mathbf{7} \) & 6 & \( \mathrm{C} \) & 2 \\ \hline \( \mathbf{8} \) & 7 & \( \mathrm{~B} \) & 1 \\ \hline \( \mathbf{9} \) & 8 & \( \mathrm{C} \) & 2 \\ \hline \( \mathbf{1 0} \) & 9 & \( \mathrm{~A} \) & 1 \\ \hline \( \mathbf{1 1} \) & 10 & \( \mathrm{~B} \) & 1 \\ \hline \( \mathbf{1 2} \) & 11 & \( \mathrm{~A} \) & 1 \\ \hline \( \mathbf{1 3} \) & \( \mathbf{1 2} \) & \( \mathrm{B} \) & 1 \\ \hline \( \mathbf{1 4} \) & 13 & \( \mathrm{C} \) & 2 \\ \hline \( \mathbf{1 5} \) & 14 & \( \mathrm{C} \) & 2 \\ \hline \( \mathbf{1 6} \) & 15 & \( \mathrm{C} \) & 2 \\ \hline \( \mathbf{1 7} \) & 16 & \( \mathrm{~B} \) & 2 \\ \hline \( \mathbf{1 8} \) & 17 & \( \mathrm{C} \) & 1 \\ \hline \( \mathbf{1 9} \) & 18 & \( \mathrm{~B} \) & 1 \\ \hline \( \mathbf{2 0} \) & 19 & \( \mathrm{C} \) & 1 \\ \hline \( \mathbf{2 1} \) & 20 & \( \mathrm{~B} \) & 1 \\ \hline \( \mathbf{2 2} \) & 21 & \( \mathrm{C} \) & 2 \\ \hline \( \mathbf{2 3} \) & 22 & \( \mathrm{~B} \) & 1 \\ \hline \( \mathbf{2 4} \) & 23 & \( \mathrm{C} \) & 2 \\ \hline \( \mathbf{2 5} \) & 24 & \( \mathrm{~A} \) & 1 \\ \hline \( \mathbf{2 6} \) & 25 & \( \mathrm{~B} \) & 1 \\ \hline \( \mathbf{2 7} \) & \( \mathbf{2 6} \) & \( \mathrm{C} \) & 2 \\ \hline \( \mathbf{2 8} \) & 27 & \( \mathrm{C} \) & 2 \\ \hline \( \mathbf{2 9} \) & 28 & \( \mathrm{~A} \) & 1 \\ \hline \( \mathbf{3 0} \) & 29 & \( \mathrm{~B} \) & 1 \\ \hline \( \mathbf{3 1} \) & 30 & \( \mathrm{~B} \) & 2 \\ \hline \( \mathbf{3 9} \) & & & \end{tabular} - Page 56, problems 25 (for part c, you would manually construct the stem-andleaf display)
