1. Four students had low scores that might be considered outliers. Removing these possible outliers, which statement correctly describes the shape, center, and spread of thedistribution?

a. The distribution is roughly symmetric with center near 111 and range from 86 to 136.

b. The distribution is slightly rightskewed with center near 104 and range from 72 to 136.

c. The distribution is slightly leftskewed with center near 110 and range from 86 to 136.

d. The distribution is roughly symmetric with center near 104 and range from 8 to 13.

2. We often read that IQ scores for large populations are centered at 100. What percent of these 78 students have scores above 100? (Round the final answer to one decimalplace.)
