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.
举一反三
- When a range of values is used to estimate a population parameter, it is called _______.
- When a range of values is used to estimate a population parameter, it is called _______. A: a point estimate B: an interval estimate C: a statistical parameter D: a range estimate
- An unbiased estimator is a sample statistic, which has an expected value equal to the value of the population parameter.
- The problem with relying on a point estimate of a population parameter is that:
- In order to construct a confidence interval estimate of the population mean, the value of the population mean is needed.
