2. [-/4 Points] DETAILS BBBASICSTAT8 7.5.013.S. MY NOTES ASK YOUR T Coal is carried from a mine in West Virginia to a power plant in New York in hopper cars on a long train. The automatic hopper car loader is set to put 64 tons of coal into e into each car are normally distributed, with mean / = 64 tons and standard deviation a = 0.6 ton. LA USE SALT (a) What is the probability that one car chosen at random will have less than 63.5 tons of coal? (Round your answer to four decimal places.) (No Response) (b) What is the probability that 21 cars chosen at random will have a mean load weight x of less than 63.5 tons of coal? (Round your answer to four decimal places.) (No Response) (c) Suppose the weight of coal in one car was less than 63.5 tons. Would that fact make you suspect that the loader had slipped out of adjustment? Yes O No Suppose the weight of coal in 21 cars selected at random had an average x of less than 63.5 tons. Would that fact make you suspect that the loader had slipped out o Yes, the probability that this deviation is random is very small. Yes, the probability that this deviation is random is very large. O No, the probability that this deviation is random is very small. No, the probability that this deviation is random is very large. Need Help? Read It Watch It
