The document discusses computing the point estimate of a population mean. It provides instructions on how to calculate the point estimate using sample data. Specifically, it explains that the sample mean is the best point estimate of the population mean. An example is provided where 6 samples of 10 bottles of coconut juice each were taken and the mean of each sample was calculated. The mean of all the sample means was then found to be 497.83 ml, which provides a point estimate that is slightly less than the claimed volume of 500 ml per bottle.

9. The seven dwarfs wanted to know if her
claim is true. They went to six coconut farms and
took random samples of 10 such bottles and
obtained the capacity, in ml, of each bottle.

LESSON
An ESTIMATE is a value or a range of values that approximate a
parameter. It is based on sample statistics computed from sample data.
ESTIMATION is the process of determining parameter values.
POINT ESTIMATE is a specific numerical value of a population parameter.
The sample mean is the best point estimate of the population mean.
