In 2017 a pollution index was calculated for a sample of cities in the eastern states using data on air and water pollution Assume the distribution of pollution lltdiCeS is unimodai and symmetric The mean of the distribution was 37 1 points With a standard deviation of 11.3 points Compiete parts (a) through (c) beiow a. What percentage of eastern cities would you expect to have a pollution index between 14.5 and 59.7 points? % (Type a whole number) b What percentage of eastern cities wouid you expect to have a pollution index between 25 8 and 48.4 points? \"A. (Type a whole number) c The pollution index for an eastern city, in 2017, was 45.3 points. Based on this distribution, was this unusually high? Explain. O A. No, because 45 3 falls Within two standard deviations away from the mean, and it is therefore not an unusually high pollution index 0 B. Yes, because 45 3 falls Within two standard deviations of the mean. so it is therefore an unusually high poilution index ' O C. No, because 45 3 falls exactly two standard deviations away from the mean, and it is therefore not an unusually high pollution index 0 D. Yes, because 45 3 falls within three standard deviations ot the mean, so it is therefore an unusually high pollution index
