Question 1

If the sample size (n) is large (say,n≥ 30), then it is safe to model the sampling distribution of\(\style{font-family:Times New Roman;}{\overline x}\)as a:

discrete distribution.


continuous distribution.


log-normal distribution.


normal distribution.



Question 2

If the sample size is large (≥ 30), then, regardless of the population distribution, which of the following summarizes the sampling distribution of random variable\(\style{font-family:Times New Roman;}{\overline X}\)?

\(\style{font-family:'Times New Roman'}{\overline X\dot\sim N(\mu_\overline X=\mu\;,\;\sigma_\overline X=\sigma/\sqrt n)}\)


\(\style{font-family:'Times New Roman'}{\overline X\dot\sim N(\mu_\overline X=\mu\;,\;\sigma_\overline X=\sigma/n)}\)


\(\style{font-family:'Times New Roman'}{\overline X\dot\sim N(\mu_\overline X=\mu\;,\;\sigma_\overline X=\sigma)}\)


\(\style{font-family:'Times New Roman'}{\overline X\dot\sim N\left(\mu_\overline X=\mu\;/\sqrt n,\;\sigma_\overline X=\sigma/\sqrt n\right)}\)
