Extracted text: 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. Compute a 5% trimmed mean for Upper Canyon and Lower Canyon. Round your answer to the nearest thousandth. 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 8 1 1 0 6 7 2 11 3 0 1 10 2 1 The 5% trimmed mean for Lower Canyon is 2.889 and for Upper Canyon is 3.500. The 5% trimmed mean for Lower Canyon is 2.364 and for Upper Canyon is 3.071. The 5% trimmed mean for Lower Canyon is 3.500 and for Upper Canyon is 2.889. The 5% trimmed mean for Lower Canyon is 3.000 and for Upper Canyon is 4.500. The 5% trimmed mean for Lower Canyon is 2.455 and for Upper Canyon is 3.857.
