An article suggests that substrate concentration (mg/cm³) of influent to a reactor is normally distributed with =0.50 and =0.06.

(Round your answers to four decimal places.)

(a)What is the probability that the concentration exceeds0.60?

(b)What is the probability that the concentration is at most0.30?

(c)How would you characterize the largest 5% of all concentration values? The largest 5% of all concentration values are above _________ mg/cm³.
