Question

fill in the blank.
a ______ is a single value used to approximate a population parameter.
a is a single value used to approximate a population parameter.
sample size
confidence interval
point estimate
continuity correction

Explanation:

A point estimate is a single value that is used to approximate a population parameter. For example, the sample mean $\bar{x}$ is a point estimate of the population mean $\mu$. A sample size is the number of observations in a sample. A confidence interval is an interval estimate, not a single - value estimate. Continuity correction is a correction factor used when approximating a discrete distribution with a continuous distribution.

Answer:

point estimate
