= 8 scores (in performance improvement).

Step-by-step explanation:

Average standardized-test score for the first 10 high schools = 69

Average standardized-test score for the second 10 high schools = 70

After 6 months:

Average standardized-test score for the first 10 high schools offered test preparation classes = 78

The change in the average standardized-test score for the first 10 high schools = 9 (78 - 69)

Average standardized-test score for the second 10 high schools not offered test preparation classes = 71

The change in the average standardized-test score for the second 10 high schools not offered the prep = 1 (71 - 70)

The estimated impact of the experiment of offering test preparation classes is:

= 9 - 1  

= 8.
