Suppose the horses in a large stable have a mean weight of 992lbs, and a standard deviation of 141lbs. what is the probability that the mean weight of the sample of horses would differ from the population mean by less than 13lbs if 37 horses are sampled at random from the stable? round your answer to four decimal places.

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 77 tons of coal into each car. the actual weights of coal loaded into each car are normally distributed, with mean μ = 77 tons and standard deviation σ = 0.9 ton. (a) what is the probability that one car chosen at random will have less than 76.5 tons of coal? (round your answer to four decimal places.) (b) what is the probability that 47 cars chosen at random will have a mean load weight x of less than 76.5 tons of coal? (round your answer to four decimal places.) (c) suppose the weight of coal in one car was less than 76.5 tons. would that fact make you suspect that the loader had slipped out of adjustment? yes no suppose the weight of coal in 47 cars selected at random had an average x of less than 76.5 tons. would that fact make you suspect that the loader had slipped out of adjustment? why? yes, the probability that this deviation is random is very small. yes, the probability that this deviation is random is very large. no, the probability that this deviation is random is very small. no, the probability that this deviation is random is very large.

He weight of a sophisticated running shoe is normally distributed with a mean of 15 ounces. (a) what must the standard deviation of weight be in order for the company to state that 97% of its shoes weight less than 16 ounces? (b) suppose that the standard deviation is actually 0.82. if we sample 6 such running shoes, find the probability that exactly 3 of those shoes weigh more than 16 ounces.
