A parameter (designated by a bulls-eye) is being estimated by a statistic from a sample of size n=5n=5 (designated by smiley faces). If a similar picture was observed for every possible sample of size n=5n=5, what is the best description of the sampling distribution of the statistic? a. The sampling distribution of our statistic is accurate but not precise. b. The sampling distribution of our statistic is neither precise nor accurate. c. The sampling distribution of our statistic is precise but not accurate. d. The sampling distribution of our statistic is both precise and accurate.
