Question 9(Multiple Choice Worth 2 points)
(Box Plots MC)
The box plot represents the number of students who used a computer in the media center in 12 days.
A box plot uses a number line from 28 to 84 with tick marks every 1 unit. The box extends from 44 to 70 on the number line. A line in the box is at 60. The lines outside the box end at 30 and 82. The graph is titled Computer Use, and the line is labeled Number of Students.
Determine which of the following is the five-number summary of the data.
Min: 30, Q1: 48, Median: 62.5, Q3: 70, Max: 82
Min: 35, Q1: 48, Median: 61.5, Q3: 70, Max: 79
Min: 30, Q1: 44, Median: 60, Q3: 70, Max: 82

12, 14, 15, 15, 16, 16, 16, 17, 18, 18 ,19, 20, 22, 25
If another plant with a height of 13 inches is added to the data, how would the mean be impacted?
The mean would stay the same value of about 17.1 inches.
The mean would decrease in value to about 17.1 inches.
The mean would stay the same value of about 17.4 inches.

(Histograms and Line Plots MC)
A surfer recorded the following values for how far the tide rose, in feet, up the beach over a 15-day period.
2, 7, 8, 9, 12, 13, 14, 15, 16, 18, 20, 20, 21, 24, 25
Which of the following histograms best represents the data collected?
A histogram titled Tides For 15 Days with an x-axis labeled Measurement In Feet with intervals of 1 to 5, 6 to 10, 11 to 15, 16 to 20, and 21 to 25. The y-axis is labeled Frequency and starts at 0 with tick marks every one unit up to 7. There is a shaded bar above 1 to 5 that stops at 2, above 6 to 10 that stops at 4, above 11 to 15 that stops at 2, above 16 to 20 that stops at 4, and above 21 to 25 that stops at 3.
