Suppose an x-distribution has mean ? = 2. Consider two corresponding x distributions, the first based on samples of size n = 49 and the second based on samples of size n = 81.   (a) What is the value of the mean of each of the two x distributions? For n = 49, ?x=  For n = 81, ?x=    b) For which x distribution is P(x > 2.50) smaller? Explain your answer. The distribution with n = 49 because the standard deviation will be larger. The distribution with n = 81 because the standard deviation will be smaller.     The distribution with n = 49 because the standard deviation will be smaller. The distribution with n = 81 because the standard deviation will be larger.   c) For which x distribution is P(1.50 < x< 2.50) greater? Explain your answer. The distribution with n = 49 because the standard deviation will be larger. The distribution with n = 81 because the standard deviation will be smaller.    The distribution with n = 49 because the standard deviation will be smaller. The distribution with n = 81 because the standard deviation will be larger.
