Answer:

The point estimate of population mean is 21.6.

Explanation:

A point estimate is a numerical value that is used to estimate the value of the parameter under study.

The point estimate is calculated using the sample values.

For example, sample (
\bar x) is the point estimate of population mean (μ), sample standard deviation (s) is the point estimate of population standard deviation (σ), sample proportion (
\hat p) is the point estimate of population proportion (p).

It is provided that the sample mean of 100 items is,


\bar x=21.6

Then the point estimate of population mean is:


\mu=\bar x=21.6

Thus, the point estimate of population mean is 21.6.
