A can company reports that the number of breakdowns per 8-hour shift on its machine operated assembly line follows a Poisson distribution with a mean of 1.5. What is the probability of exactly three breakdowns on the midnight shift? What is the probability of greater than two breakdowns in one hour? What is the probability that the time between two successive breakdowns is at most three hours? If two hours have gone by without a breakdown, what is the probability...

A company has 3 machines: A, B, and C. The number of breakdowns per week is distributed Poisson. On average, machine A breaks down .4 times per week, machine B breaks down .45 times per week and machine C breaks down .9 times per week. The probability that there are 2 breakdowns in one week is _____ (round to 4 decimal places).

The Local Bottling Company has just installed a new bottling process that will fill 16-ounce bottles of the popular Paradise Classic Cola soft drink. Both overfilling and underfilling bottles are undesirable: Underfilling leads to customer complaints and overfilling costs the company considerable money. In order to verify that the filler is set up correctly, the company wishes to see whether the mean bottle fill, μ, is close to the target fill of 16 ounces. To this end, a random sample...
