15) Group-A (a) Let 1 and 2 be unbiased estimators for the parameter 0. Is the estimator 03 = 0.2 0₁ + 0.8 0₂ an unbiased estimator, if yes, why, if not, why not? Explain your answer. (b) Suppose there are n individuals in a group each shooting once at the same target, where each individual can independently hit the target with the probability of 90%. Assuming the probability that at least one of them hits the target is 99.99%, determine the value of the integer n. Use a calculator to simplify your answer. (c) Noting that you do not need to explain your answer, state whether the following statement regarding the sample mean is true or false: "An increase in the number of samples or an increase in the confidence level can make the confidence interval narrower."
