Transcribed Image Text:The Grand Canyon and the Colorado River are beautiful, rugged, and sometimes dangerous. Thomas Myers is a physician at the park
clinic in Grand Canyon Village. Dr. Myers 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 (Source: Fateful Journey by Myers, Becker,
Stevens).
Upper Canyon: Number of Injuries per Landing Point Between North Canyon
and Phantom Ranch
2 3 1 1 3 4 6 9 3 1 3
Lower Canyon: Number of Injuries per Landing Point Between Bright Angel
and Lava Falls

n USE SALT
(a) Compute the mean, median, and mode for injuries per landing point in the Upper Canyon. (Enter your answers to one
decimal place.)
mean
median
mode
(b) Compute the mean, median, and mode for injuries per landing point in the Lower Canyon. (Enter your answers to one
decimal place.)
mean
median
mode
(c) Compare the results of parts (a) and (b).
The Lower Canyon mean is greater, while the median and mode are the same.
The mean, median, and mode are greater for the Upper Canyon.
The Lower Canyon mean is greater, while the median and mode are less.
The mean, median, and mode are greater for the Lower Canyon.
(d) The Lower Canyon stretch had some extreme data values. Comput
5% trimmed mean for this region, and compare this
result to the mean for the Upper Canyon computed in part (a). (Enter your answer to 2 decimal places.)
The trimmed mean is closer to the Upper Canyon mean.
The trimmed mean is the same as the Upper Canyon mean.
The trimmed mean is further away from the Upper Canyon mean.
The trimmed mean is the same as the untrimmed Lower Canyon mean.
