Question

Based on the stem lot, which of the following is a correct comparison of the eastern and western states expenditures?A The western states exhibit more variability in their expenditures than the eastern states.B The eastern states have, on average, a higher per-pupil expenditures than the western states.C The distribution of per-pupil expenditures in the eastern states is more symmetric than the distribution of the western states.D The distribution of the western states’ per-pupil expenditure is skewed left, while the distribution of the eastern states’ per pupil expenditure is skewed right.E valid conclusions comparing the distributions cannot be made, since there is a different number of states in each group.

Answer 1

B. The eastern states have, on average, higher per-pupil expenditures than the western states.

Step-by-step explanation:

Taking into account the plot, we can see that in eastern states there is more variability, the numbers are all around the plot. However, in western states, the numbers are more in the top part of the plot. So, we can conclude that on average, the per-pupil expenditure is higher in Eastern states than the western states.

Therefore, the answer is:

B. The eastern states have, on average, higher per-pupil expenditures than the western states.
