Andy is alone in the wilderness and eager to get back to camp. Looking at his map (shown below), Andy sees that he might be able
to cut through the brush instead of hiking the trail.
How much shorter would it be for Andy to cut through the brush than hike the trail?
___km
Round the final answer to the nearest tenth of a kilometer. Do not round intermediate calculations.

Answer:
The mean of the distribution of sample means is 27.6
Step-by-step explanation:
We are given the following in the question:
Mean, μ = 27.6
Standard Deviation, σ = 39.4
We are given that the population is a bell shaped distribution that is a normal distribution.
Sample size, n = 173.
We have to find the mean of the distribution of sample means.
Central Limit theorem:
- It states that the distribution of the sample means approximate the normal distribution as the sample size increases.
- The mean of all samples from the same population will be approximately equal to the mean of the population.
Thus, we can write:
Thus, the mean of the distribution of sample means is 27.6
