A population has parameters $\mu = 193.6$ and $\sigma = 43.1$. You intend to draw a random sample of size $n = 145$. What is the mean of the distribution of sample means? $\mu_{\bar{x}} =$ What is the standard deviation of the distribution of sample means? (Report answer accurate to 2 decimal places.) $\sigma_{\bar{x}} = $

Step 1
6. The standard deviation of the distribution of sample means, also known as the standard error, is equal to the population standard deviation divided by the square root of the sample size. So, the standard deviation of the distribution of sample means is σ/√n = Show more…
