Question 12

The Grand Canyon and the Colorado River are beautiful, rugged, and sometimes dangerous. Assume there is a physician at the park clinic in Grand Canyon Village. Suppose the physician has recorded (for a 5-year period) the number of visitor injuries at different landing points for commercial boat trips down the Colorado River in both the Upper and Lower Grand Canyon.

Upper Canyon: Number of injuries per Landing Point Between North Canyon and Phantom Ranch
4	5	3	3	5	6	8	11	5	3	5

Lower Canyon: Number of injuries per Landing Point Between Bright Angel and Lava Falls
10	3	3	0	8	9	4	14	5	0	3	13	4	3

The mean, median, and mode for Upper Canyon are 5.273, 5.0, and 5, respectively.

The mean, median, and mode for Lower Canyon are 5.643, 4.0, and 3, respectively.

Compare the mean, median, and mode found in Upper Canyon and Lower Canyon, respectively.

Group of answer choices

Lower Canyon mean is smaller than Upper Canyon, Lower Canyon median is smaller than Upper Canyon, and Lower Canyon mode is smaller than Upper Canyon.
