The amount of pollutants that are found in waterways near large cities is normally distributed with mean 9.9 ppm and standard deviation 1.5 ppm. 12 randomly selected large cities are studied. Round all answers to 4 decimal places where possible. What is the probability that one randomly selected city's waterway will have more than 9 ppm pollutants? For the 12 cities, find the probability that the average amount of pollutants is more than 9 ppm. For part d), is the assumption that the distribution is normal necessary? NoYes Find the IQR for the average of 12 cities.Q1 = ppmQ3 = ppmIQR: ppm
The height of American women is believed to follow a normal distribution with mean μ = 5.38 feet and standard deviation σ = 0.2083 feet. (b) A study randomly selects 30 American women. What is the probability that the mean height of women in this sample is greater than 5.5 feet? (c) Another study randomly selects 50 American women. Will there be a lower or higher probability that the mean height of the 50 women in this sample is greater than 5.5 feet, compared to the study in part (b)? Explain. (d) Instead, for which of the two studies from parts (b) and (c) there is a higher probability that the mean height of the women in the sample is between 5.33 and 5.43 feet? Explain.
