Answer the following questions for the sampling distribution of the sample mean shown to the right. (a) What is the value of $\mu_{\bar{x}}$ ? (b) What is the value of $\sigma_{\bar{x}}$ ? (c) If the sample size is $n=16$, what is likely true about the shape of the population? (d) If the sample size is $n=16,$ what is the standard deviation of the population from which the sample was drawn?
Sampling Distributions
Distribution of the Sample Mean
Find the standard deviation of the sampling distribution of sample means using the given information. Round to one decimal place, if necessary. μ=41 and σ=8 ; n=16

For random samples of size $n=16$ selected from a normal distribution with a mean of $\mu=75$ and a standard deviation of $\sigma=20,$ find each of the following: a. The range of sample means that defines the middle $95 \%$ of the distribution of sample means b. The range of sample means that defines the middle $99 \%$ of the distribution of sample means.
