Considering the sample mean, the best estimate for the mean monthly electric bill for all residents of the local apartment complex is of $86.
How to find the point estimate of a population parameter?
The point estimate for the population parameter is found according to the parameter for a sample from the population. For example:
- The best point estimate for the population mean is the sample mean.
- The best point estimate for the population standard deviation is the sample standard deviation.
In this problem, the mean bill for 132 residents is of $86, hence the best estimate for the mean monthly electric bill for all residents of the local apartment complex is of $86.
