A population has mean $\mu =112.2$ and $\sigma =47.7$. You intend to draw a random sample of size $n=123$. (a) What is the shape of the sampling distribution of means? bimodal left-skewed right-skewed normal uniform (b) What is the center of the sampling distribution of means? ${\mu }_x=$ Round to four decimal places as needed. (c) What is the standard error of the sampling distribution of means? ${\sigma }_x=$ Round to four decimal places as needed.
