Question

Create a histogram using a technology tool. Then complete the statement.

Student Test Scores: {85, 90, 88, 92, 87, 85, 91, 89, 93, 88, 90, 85, 92, 91, 89, 86, 88, 87, 89, 90}
. Begin the histogram at 84, and create a bin size width of 2.(1 point)
The range of scores shown on this histogram is

Answer 1

Here are the histogram bins (start = 84, width = 2) and frequencies:

- 84–86: 3
- 86–88: 3
- 88–90: 6
- 90–92: 5
- 92–94: 3

(ASCII histogram)
84–86: ###
86–88: ###
88–90: ######
90–92: #####
92–94: ###

The range of scores shown on this histogram is 84 to 94 (span = 10 points).
(For reference, the actual scores run from 85 to 93, so the data range = 8 points.)
