What is the answer

Question 7 Central Limit Theorem: Determining Sample Sum Probabilities Using the TI-84 An unknown distribution has a mean of 90 and a standard deviation of 15. A sample of size 64 is randomly drawn from the population. Given these formulas: HEz = (n) (ux) = mean of Ex Ex = (7) (ox) = standard deviation of Ex Ex = (n) (xx) + (z) (1/72) (ox) Find the sum that is 1.2 standard deviations below the mean of sums. 5616 5626 5636 5642
