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

Explanation:

In statistics, the sample mean is a fundamental concept used as an estimator. A point estimate is a single value estimate of a population parameter. The sample mean $\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}$ (where $x_{i}$ are the sample observations and $n$ is the sample size) is unbiased (under appropriate conditions) and has desirable properties (such as minimum variance in some cases among unbiased estimators for normal populations) for estimating the population mean $\mu$.

Answer:

sample mean
