Question

Suppose an x distribution has mean 6 Consider two corresponding x distributions the first based on samples of size n 49 and the second based on samples of size n 81 USE SALT a What is the value of the mean of each of the two x distributions For n 49 x For n 81 Hx b For which x distribution is P x 7 50 smaller Explain your answer O The distribution with n 81 because the standard deviation will be smaller O The distribution with n 49 because the standard deviation will be larger O The distribution with n 49 because the standard deviation will be smaller O The distribution with n 81 because the standard deviation will be larger c For which x distribution is P 4 50 x 7 50 greater Explain your answer O The distribution with n 81 because the standard deviation will be smaller The distribution with n 49 because the standard deviation will be smaller O The distribution with n 49 because the standard deviation will be larger O The distribution with n 81 because the standard deviation will be larger
