Concept explainers
To construct: a similar picture that shows the idea of the sampling distribution of a sample mean.
Explanation of Solution
Graph:
The sampling distribution of the sample mean is about normal when the sample is enough large (due to the central limit theorem; sample is assumed to be enough large
The mean of the sampling distribution of the sample mean is equal to the population mean
The standard deviation of the sampling distribution of the sample mean is the population standard deviation
Thus the sampling distribution of the sample mean is about normal with mean
