Determine mu subscript x overbar and sigma subscript x overbar from the given parameters of the population and sample size. equals 56, sigma equals 16, nequals27.

Step-by-step explanation:

Given that a population has mean as 56 and std deviation as 16.

The above are population parameters.

Whenever random samples are drawn for large size, by central limit theorem we have the sample mean will follow a normal distribution with mean = population mean and std error = std deviation/sqrt of n

Hence here sample bar will be normal with

Mean of x bar =

Std error of x bar =
