To Explain: that a statistics is an unbiased estimator of a parameter when
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
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)
