The average production cost for major movies is 69 million dollars and the standard deviation is 18 million dollars. Assume the production cost distribution is normal. Suppose that 8 randomly selected major movies are researched. Answer the following questions. Round all answers to 4 decimal places where possible. What is the distribution of XX? XX ~ N What is the distribution of ¯xx¯? ¯xx¯ ~ N For a single randomly selected movie, find the probability that this movie's production cost is between 64 and 70 million dollars.
