The point estimate of the population mean number of units sold per month is given by:
90.
How to obtain the point estimate of a parameter?
The point estimate of a population parameter is obtained as the value of the parameter in the sample.
The parameter that we want to obtain the estimate in this problem is:
The mean.
The sample in this problem is given by:
94, 85, 85, 94, 92.
(number of units sold each month).
The sample mean is given by the sum of all observations in the sample divided by the number of observations, hence it is obtained as follows:
Mean = (94 + 85 + 85 + 94 + 92)/5 = 90.
For the fraction, we have that:
- The numerator is the sum of all observations.
- The denominator is the number of observations.
