Chlorine concentration in a municipal water supply is a uniformly distributed random variable that ranges between 0.74 ppm and 0.98 ppm.
Note: base = 0.98-0.74 = 0.24 height = 1/0.24 = 4.17
Calculate the mean chlorine concentration.:: (0.74+0.98)/2 = 0.86
-----------------------------------
Chlorine concentration in a municipal water supply is a uniformly distributed random variable that ranges between 0.74 ppm and 0.98 ppm.
Calculate the standard deviation.:: (0.98-0.74)/6 = 0.08
-----------------------------------
Chlorine concentration in a municipal water supply is a uniformly distributed random variable that ranges between 0.74 ppm and 0.98 ppm.
Calculate the probability that the chlorine concentration will exceed 0.80 ppm
z(0.8-0.86)/0.08 = -0.75 = (3/4)std below the mean
Ans: 0.50 + (0.75)(1/6) = 0.625

Chlorine concentration in a municipal water supply is a uniformly distributed random variable that ranges between 0.74 ppm and 0.98 ppm.
Calculate the probability that the chlorine concentration will be between 0.80 ppm and 0.90 ppm
(0.9-0.8) = 0.1(1/6) = 0.0167
