Dirty air: The federal government has enacted maximum allowable standards for air pollutants such as ozone. Let X be the number of days per year that the level of air pollution exceeds the standard in a certain city. The probability distribution of X i given by X 0 2 4 P(x) 0.32 0.39 0.17 0.08 0.04 Send data to Excel Part 1 of 6 (a) Find P(4). P(4) 0.04(b) Find P[3 or fewer). H3 or fewer) = (1:) Find the probability that the standard is exceeded an at least three days. The probability at the standard is exceeded an at least three days is . {d} Find the probability that the standard is exceeded on more than one day. The probability that the standard is exceeded an more than one day is . (e) Compute the mean J . Round the answer to two decimal places. H = 0.89 X 5 Part 6 of 6 (f) Compute the standard deviation 6 . Round the answer to three decimal places
