A population of values has a normal distribution with mu = 165.5 and sigma = 11.6. You intend to draw a random sample of size n = 77. What is the mean of the distribution of sample means? mu_{ar{x}} = What is the standard deviation of the distribution of sample means? (Report answer accurate to 2 decimal places.) sigma_{ar{x}} =

Step 1
The question asks for two things: the mean of the distribution of sample means (\( \mu_{\bar{x}} \)) and the standard deviation of the distribution of sample means (\( \sigma_{\bar{x}} \)) for a population that is normally distributed with a mean (\( \mu \)) of Show more…
