Two statistics are being considered for estimating the value of a population characteristic. The sampling distributions of the two statistics are shown here.

a. Suppose the actual value of the population characteristic is 50. Is Statistic I or Statistic II unbiased? If so, which one?
b. Suppose the actual value of the population characteristic is 54. In this case, neither Statistic I nor Statistic II is unbiased. Which of these two statistics would you recommend as the better estimator of the population characteristic? Explain the reasoning for your choice.
