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:

\mu_{\bar{x}} = \mu = 27.6

Thus, the mean of the distribution of sample means is 27.6
