Test scores continued For the data provided in Exercise 23, explain how you would expect the mean, median, standard deviation, range, and IQR to change (with brief explanation), if you were to:
a) Delete all the test scores between 0 and 5.
b) Change all the test scores above 50 to scores of exactly 50.

d) Delete half the test scores between 30 and 35.
e) Add 30 additional graded tests with scores all between 30 and 35.
f) Add 20 additional test papers, where 10 scored 50 and the other 10 scored 15.
g) Adjust all the test scores upward by +5. h) Double all the raw test scores so that you get percentage scores out of 100.
