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. Find the IQR for the average of 6 cities. Q1 = ppm Q3 = ppm ok IQR: ppm
