### Sampling and Descriptive StatisticsA population consists of the following five values: 2, 2, 4, 4, and 8.#### a. List all samples of size 2, and compute the mean of each sample.**Table: Samples of Size 2**| Sample | Values | Sum | Mean ||--------|--------|-----|------|| 1 | | | || 2 | | | || 3 | | | || 4 | | | || 5 | | | || 6 | | | || 7 | | | || 8 | | | || 9 | | | || 10 | | | |#### b. Compute the mean of the distribution of sample means and the population mean. Compare the two values.**Table: Comparison of Means**| | Value ||----------------------|-------|| Mean of the distribution of the sample mean | || Population mean | || Both means are | |This exercise involves calculating the mean for each possible pair of samples from the given population and then comparing these sample means with the population mean.

Solution: The population values are 2, 2, 4, 4, 8 n= 5 observation. The formula of mean is Mean…

Answered: A population consists of the following…
