The top of the escalator exists 9 feet far from the ground floor.
<h3>
How to estimate how far is the top of the escalator from the ground floor? </h3>
Let h denote the distance between the top of the escalator from the ground floor.
We have existed given that the angle of depression from the top of the escalator to the floor stands 36.84°, and the escalator exists 15 feet long.
The side h exists opposite side and 15 feet side exists hypotenuse of a right triangle.
8.993737 = h
Therefore, the top of the escalator exists 9 feet far from the ground floor.

If you are looking for decimals yes but if not then no
Answer:
The mean is 0.54 and the standard deviation is 0.05.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a sample proportion p in a sample of size n, the mean of the sampling distribution is p and the standard deviation is .
In this problem:
So
Mean 0.54
Standard deviation .
The mean is 0.54 and the standard deviation is 0.05.
