Answer:
The point estimate of population mean is 21.6.
Step-by-step 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 ([tex]\bar x[/tex]) is the point estimate of population mean (μ), sample standard deviation (s) is the point estimate of population standard deviation (σ), sample proportion ([tex]\hat p[/tex]) is the point estimate of population proportion (p).
It is provided that the sample mean of 100 items is,
[tex]\bar x=21.6[/tex]
Then the point estimate of population mean is:
[tex]\mu=\bar x=21.6[/tex]
Thus, the point estimate of population mean is 21.6.
