At a factory, 40% of the machines can be serviced in-house, with the rest requiring the company to hire an
outside specialist. Suppose that the machines that are serviced in-house have a failure rate of 20%, and that
the machines serviced by an outside specialize have a failure rate of 8%. If a random machine has failed, what
is the probability that the foreman will have to hire an outside specialist to fix it?

Joyce works in a toy factory maintaining machines. Machines should inject exactly 500 grams of plastic into a mold to make a toy plane. Joyce wonders if these toy machines might need cleaning, but it's a lot of work taking apart the machines to do a proper job. She grabs planes from 24 different machines at random and weighs them. Her average is 495 grams. She knows there's a standard devation of 10 grams for all machines (Joyce has been...

Consider buying a house whose fair market value is $500K, but you can get it for $450K. However, there is a risk: if the house has structural problems (its current condition is not OK), you will have to spend $110K to fix it. The probability that currently it’s in OK condition is estimated to be 75%; that is, P(OK) = 0.75. a) What is the expected utility (i.e., expected net gain or loss in dollars) if you buy? Someone is...

Ball Sports Inc. is considering an investment in one of two machines. The stitching machine will increase productivity from sewing 300 baseballs per hour to stitching 360 per hour. The contribution margin is $0.30 per baseball. Assume that any increased production of baseballs can be sold. The second machine applies a synthetic balata cover to golf balls. The golf ball machine will reduce labor cost. The labor cost saved is equivalent to $40 per hour. The stitching machine will cost...
