The question was: The middle 50% of the scores for the control group fall between:

Your Answer: 5-10

Answer and explanation: Your answer is incorrect. The correct answer is 8-10.
On a boxplot, the middle 50% is represented by the distance covered on the scale by the whole box. That is, for the Control Group, the middle 50% of the ratings fall between 10, or the upper bound of the box, and 8 or the lower bound of the box. 5-10 is the spread of the Control Group's scores including those scores one standard deviation from the mean.
