Question

(Type an integer or a decimal)

Answer 1

Graph 3 most closely resembles the sampling distribution of the sample means, because $\mu_{\bar{x}} = 16.7$ and $\sigma_{\bar{x}} = 0.74$ and the graph looks like a normal distribution.

(If the above one is wrong, then this will be correct.... Graph 4 most closely resembles the sampling distribution of the sample means, because $\mu_{\bar{x}} = 16.7$ and $\sigma_{\bar{x}} = 11.1$ and the graph looks like a normal distribution.)
