The Grand Canyon and the Colorado River are beautiful, rugged, and sometimes dangerous. A 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 3211257 3 2 1 1 2 5 7 8 2 1 2 Lower Canyon: Number of Injuries per Landing Point Between Bright Angel and Lava Falls 9110 5 6 3 13 2 0 1 14 11 USE SALT (a) Compute the mean, median, and mode for injuries per landing point in the Upper Canyon. What is the mean? (Round your answer to four decimal places.) 3.3 x What is the median? 3 x What is the mode? 2 (b) Compute the mean, median, and mode for injuries per landing point in the Lower Canyon. What is the mean? (Round your answer to four decimal places.) 4 What is the median? x What is the mode? 1 (c) Compare the results of parts (a) and (b). O The Lower Canyon mean is greater, while the median and mode are the same. O The mean, median, and mode are greater for the Upper Canyon. The Lower Canyon mean is greater, while the median and mode are less. O The mean, median, and mode are greater for the Lower Canyon.
