Answer:
16.35
Step-by-step explanation:
Using an inverse normal distribution, we can calculate the z score given the percentile, which can then be used to find our value.
First, we can use an inverse normal distribution calculator to figure out that the z score given the 75th percentile is 0.674.
Next, we know that the z score is (observed value - mean) / standard deviation. We can plug our values in to get
Rounding, we get x = 16.35 as our answer
Answer:
<u>20,602 feet</u> is the difference in height between the top of Mt. McKinley and the bottom of the Death Valley.
Step-by-step explanation:
Given:
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.
