- The test statistic measures how close the computed sample statistic has come to the hypothesized population parameter.
- The sample variance is an unbiased estimator of the population variance.
- When estimating population parameters, a point estimate is:? always equal to a population value.|a range of possible values for a population parameter.|the population mean.|a statistic that estimates a population parameter.
