Question 11

The administration at Warmfuzzy University gave a 7-item questionnaire to a representative sample of seniors. Each item was a statement of intention (recommend WU to others, return after graduation, give money, and so forth). The seniors simply checked the items they intended to do. A person's score was the sum of the items checked. Arrange the scores into a simple frequency distribution. Construct a histogram. $$\begin{array} { l l l l l l l l l l l l l l } 
1 & 2 & 1 & 3 & 0 & 4 & 0 & 5 & 1 & 2 & 4 & 0 & 5 & 0 \
