Answer to Problem 27E

In many samples, the values of the statistics are centred at the value of the parameter.

Explanation of Solution

A Statistic is an unbiased estimator of a parameter if the expected value of the statistic is equal to the parameter. Or equivalently, the sampling distribution of the statistic will be centred about the parameter.

This then means that in many sample, the value of the statistic is centred at the value of the parameter.

Hence, the correct option is (d)
