Suppose that the weights of trucks traveling on the interstate highway system are normally distributed. If 70% of the trucks weigh more than 12,000 pounds and 80% weigh more than 10,000 pounds, what are the mean and standard deviation for the weights of trucks traveling on the interstate system?
A. μ = 14,900; σ = 6100
B. μ = 15,100; σ = 6200
C. μ = 15,300; σ = 6300
D. μ = 15,500; σ = 6400
E. The mean and standard deviation cannot be computed from the information givenwww.crackap.com
