Organisms are present in ballast water discharged from a ship according to a Poisson process with a concentration of 10 organisms/m (the article "Counting at Low Concentrations: The Statistical Challenges of Verifying Ballast Water Discharge Standardst considers using the Poisson process for this purpose). (a) What is the probability that one cubic meter of discharge contains at least 7 organisms? (Round your answer to three decimal places.) (b) What is the probability that the number of organisms in 1.5 m of discharge exceeds its mean value by more than two standard deviations? (Round your answer to three decimal places.) (c) For what amount of discharge would the probability of containing at least 1 organism be 0.9957 (Round your answer to two decimal places.) You may need to use the appropriate table in the Appendix of Tables to answer this question.

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 70 tons of coal into each car. The actual weights of coal loaded into each car are normally distributed, with mean u = 70 tons and standard deviation o = 1.4 ton. n USE SALT (a) What is the probability that one car chosen at random will have less than 69.5 tons of coal? (Round your answer to four decimal places.) (b) What is the probability that 30 cars chosen at random will have a mean load weight x of less than 69.5 tons of coal? (Round your answer to four decimal places.) (c) Suppose the weight of coal in one car was less than 69.5 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 30 cars selected at random had an average x of less than 69.5 tons. Would that fact make you suspect that the loader had slipped out of adjustment? Why? O Yes, the probability that…

Part 1 of 2 (a) What is the mean number who weigh more than 20 pounds in a sample of 14 babies aged 6 - s months? Round the answer to two decimal places. The mean number who weigh more than 20 pounds isD. Part 2 of 2 (b) What is the standard deviation of the number who weigh more than 20 pounds in a sample of 14 babies aged 6 - 8 months? Round the answer to four decimal places. The standard deviation of the number who weigh more than 20 pounds isO.
