Question

find the mean and standard error of the mean of the sampling distribution. then sketch a graph of the sampling distribution.
the prices of photo printers on a website are normally distributed with a mean of $238 and a standard deviation of $55. random samples of size 24 are drawn from this population and the mean of each sample is determined.
the mean of the distribution of sample means is

Explanation:

Step1: Recall the formula for the mean of the sampling - distribution of the sample mean

The mean of the sampling - distribution of the sample mean $\mu_{\bar{x}}$ is equal to the population mean $\mu$.
$\mu_{\bar{x}}=\mu$

Step2: Identify the population mean

Given that the population mean $\mu = 238$. So, $\mu_{\bar{x}}=238$.

Answer:

238
