A company is evaluating a new reading program that is supposed to improve test scores. The box plots show the results of reading tests given before and after using the program. With the data, what is the most reasonable answer to the question: Does the program improve test scores?

A: No, because some students may have done worse on the post-test than on the pre-test.
B: No, because the low score of 20 and the high score of 90 did not change.
C: Yes, because the median test score increased 5 points.
D: Yes, because the same number of students scored above and below the median on each test.

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
