A computer selects a number XX from 3 to 11 randomly and uniformly. Round all answers to 4 decimal places where possible. Suppose that the computer randomly picks 40 such numbers.  What is the distribution of ¯xx¯ for this selection of numbers. ¯xx¯ ~ N(Incorrect,Incorrect) What is the probability that the average of 40 numbers will be less than 6.1?

Nissa is randomly pulling the medical records of a hospital's patients and collecting the records of those who have multiple stays at this hospital. Assume that 27% of all patients who have ever stayed at this hospital have multiple stays. What is the probability that the first multiple stays patient record that Nissa comes across is the fourth one she pulls? Use a TI-83, TI-83 Plus, or TI-84 calculator to find the probability. • Round your answer to three decimal places.
