Question
_____ Suppose a hypothesis test has a P_value of 0.82. What conclusion can be made? A. Since the P-value is very large, fail to reject H_0. B. Since the P-value is very large, a Type I error was made. Reject H_0. C. Without a value for alpha, we have nothing to compare the P-value to, so we cannot make a decision. D. With no critical value, we have nothing to compare the P-value to, so we cannot make a decision. _____ Which of the following is the best definition of what it means for a statistic theta to be an unbiased estimator of the parameter theta. A. If the value of theta is known, then sigma is zero for theta. B. The mean E[theta] = theta. In other words, all possible values of theta are centered around theta. C. As n rightarrow infinity, the standard deviation of theta converges to zero. In other words, as n rightarrow infinity, the possible values of theta are more and more tightly centered around the value of theta. D. All of the above.Explanation / Answer
32) option A is correct
33) option D is correct , as all of the above options are necessary for an unbaised estimator
