Question

Suppose an x distribution has mean 2 Consider two corresponding x distributions the first based on samples of size n 45 and the second based on samples of size n 81 LAUSE SALT a What is the value of the mean of each of the two x distributions for n 49 distribution for n 81 distribution 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 81 because the standard deviation will be larger The distribution with n 49 because the standard deviation will be smaller The distribution with n 81 because the standard deviation will be smaller The distribution with n 49 because the standard deviation will be larger
