The Lower Canyon stretch had some extreme data values Comput

The Lower Canyon stretch had some extreme data values. Compute a 5% trimmed mean for this region, and compare this result to the mean for the Upper Canyon computed in part (a)

Lower Canyon:	Number of Injuries per Landing Point Between Bright Angel
	and Lava Falls

5% trimmed mean is obtained by taking the average of the data values after removing the top and the bottom 5% of the data

We arrange the data in the ascending order.

5% of 14 data points = 0.05 * 14 = 0.70 -----> Rounded off to 1

So we remove the top and the bottom value.
