Use the following to answer the questions below:

Scores on an exam (out of 100 points) given in a large introductory statistics course are displayed in the provided histogram.

A histogram describes the results of exam scores. The horizontal axis is labeled, Exam scores and has markings from 72 to 92 in increments of 4. The vertical axis is labeled, frequency and ranges from 0 to 16 in increments of 2. The plotted bars are approximately bell-shaped. From 70 to 94, the bars extend up to counts, 2, 3, 7, 12, 13, 15, 14, 13, 10, 7, 3, and 2. All values are approximate.
