Question

fill in the blank
the______is the best point estimate of the population mean
the is the best point estimate of the population mean
sample size
sample mean
sample data
sample standard deviation

Explanation:

In statistics, the sample mean is a commonly used estimator for the population mean. It is calculated by summing up all the values in a sample and dividing by the number of observations. According to the properties of estimators (such as unbiasedness in many cases when certain conditions are met), the sample mean is a good candidate for estimating the population mean. The sample size is just the number of observations in the sample, sample data is the actual data points, and the sample standard deviation is a measure of the spread of the sample data, not directly an estimator for the population mean.

Answer:

sample mean
