Mt. McKinley, which is the highest elevation in North America, is 20,320 feet above sea level.
Death Valley, which is the lowest elevation in North America, is 282 feet below sea level.
Now, to find the difference in height between the top of Mt. McKinley and the bottom of the death valley.
<em>Height of Mt. McKinley above sea level = 20,320 feet.</em>
<em>Height of Death Valley below sea level = 282 feet.</em>
Now, to get the difference in height between the top of Mt. McKinley and the bottom of the Death Valley by adding both the heights:
Therefore, 20,602 feet is the difference in height between the top of Mt. McKinley and the bottom of the Death Valley.

The critical value for the 95% confidence interval is z = 1.96.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of
So it is z with a pvalue of , so z = 1.96.
The critical value for the 95% confidence interval is z = 1.96.
