"A corporation is trying to decide whether to open a new factory
outlet store. The store will have high, medium, or low demand.
Before it decides whether to open the store, the corporation can
pay $8,000 immediately for a market survey. The market survey can
predict 'high,' 'medium,' or 'low' demand. If the actual demand of
the store will be high, there is a 0.51 probability the survey will
predict 'high' demand, a 0.09 probability the survey will predict
'medium'...

A mortgage company classifies its borrowers into three
categories: Low Risk, Medium Risk, and High Risk. From experience,

2% of low risk borrowers eventually default on their
mortgages.
7% of medium risk borrowers eventually default on their
mortgages.
13% of high risk borrowers eventually default on their
mortgages.
The mortgages for 117 high risk borrowers are put together into
one portfolio. The company determines that they will profit on the

Based on the number of voids, a ferrite slab is classied as
either high, medium, or low. Historically, 5% of the slabs are
classied as high, 90% as medium, and 5% as low. A sample of 20
slabs is selected for testing. Let X; Y; and Z denote the number of
slabs that are independently classied as high, medium, and low,

Based on the number of voids, a ferrite slab is classified as
either high medium or low. Historically, 5% of the slabs are
classified as high, 83% as medium and 12% as low. A sample of 20
slabs is selected for testing. Let X, Y, and
Z denote the number of slabs that are independently
classified as high, medium, and low, respectively. Determine the
following. Round your answers to four decimal places (e.g.
