Coal is carried from a mine in West Virginia to a weights of coal loaded into each car are normally distributed, with mean μ-56 tons and standard deviation σ-1.1 ton. Notes Ask Your power plant in New York in hopper cars on along train. The automatic hopper car lader is set to put 56 tons oral neo each ar·The actual (e) What is the probability that one car chosen at random will have less than 55.5 tons of coal? (Round your answer to four decimal places.) (b) What is the probability that 40 cars chosen at random will have a mean load welight x of less than 55.5 tons of coal? (Round your answer to four decimal places.) (c) Suppose the weight of coal in one car was less than 5S.5 tons. Would that fact make you suspect that the loader had slipped out of adjustment? O Yes O No Suppose the weight of coal in 40 cars selected at random had an average of less than 55.5 tons Would that fact make you suspect that the loader had sipped out of adjustment? Why? Yes, the probability that this deviation is random is very smat O Yes, the probability that this deviation is random is very large O No, the probability that this deviation is random is very small O No, the probability that this deviation is random is very large Need Help?ath nit Answer Save Progress Practice Anothar Vension
