For a project in their statistics class, Alex and Tempe studied the impact of different types of background music on
students' ability to remember words from a list they were allowed to
study for 5 min. Here is a list of how many words one group of students
who listened to Beethoven's Fifth Symphony were able to remember.
11 12 23 15 14 15 14 15
10 14 15 9 11 13 25 11
13 13 12 20 17 23 11 12
12 11 20 20 12 12 19 13
15 10 14 11 7 17 13 18
(a) Make a histogram that effectively displays the distribution of words recalled.
