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:
Thus, we can write:
[tex]\mu_{\bar{x}} = \mu = 27.6[/tex]
Thus, the mean of the distribution of sample means is 27.6
