Question

question 8
when the sampling distribution of a statistic centers exactly around the parameter it estimates we can say that the statistic is which of the following?
a. unbiased
b. normally distributed
c. equal to the parameter
d. statistically significant

Explanation:

The definition of an unbiased statistic is that the sampling - distribution of the statistic is centered exactly around the parameter it estimates. A normally distributed statistic just has a particular shape of distribution and is not related to centering around the parameter. A statistic is not always equal to the parameter. Statistical significance is about the probability of observing a result under a null - hypothesis and not about centering of the sampling distribution.

Answer:

A. Unbiased
