om 14 days Week 9: Chapter 7 - Central Limit Theorem (Mean) Score: 5/25 5/8 answered .Question 6 The amount of pollutants that are found in waterways near large cities is normally distributed with mean 9.7 ppm and standard deviation 1.4 ppm. 6 randomly selected large cities are studied. Round all answers to 4 decimal places where possible. a. What is the distribution of X? X - N b. What is the distribution of ? & - N( Proctor c. What is the probability that one randomly selected city's waterway will have more than 9 ppm pollutants? d. For the 6 cities, find the probability that the average amount of pollutants is more than 9 ppm. e. For part d), is the assumption that the distribution is normal necessary? O NoO Yes f.
