Question 868668: In a certain place, the October energy consumption levels for duplexes are found to be normally distributed with a mean of 1030 kwh and a standard deviation of 22.2 kwh. What is the probability that for a randomly seleceted duplex, the energy consumption in October is more than 987 kwh?
Answer by ewatrrr(24785) (Show Source): You can put this solution on YOUR website!
z = (987-1030)/22.2 = -1.9369
P(z > -1.9369) = 1-.0264 = .9736 0r 97.36%
