Five subjects were instructed to get various amounts of sleep. Subjects were then given a list of 20 terms to remember and were tested on them 30 minutes later. The tests were calculated by the percent answered correctly. Below is a chart showing the age, gender, and amount of sleep for each subject. Create a histogram to represent the data for analysis.
