A production facility employs 6 workers on the day shift,5 workers on the swing shift, and 4 workers on the graveyardshift. A quality control consultant is to select 3 of these workers for in-depth interviews. Suppose the selection is made insuch a way that any group of 3 workers has the same chance of being selected as does any other group (drawing 3 shipswithout replacement from among 15).a. How many selections result in all 3 workers coming from the graveyard shift ?b. What is the probability that 2 selected workers will be from the day shift and 1 from the graveyard shift?(Write your answer in the format: 0.xxxx)c. What is the probability that all 3 selected workers will be from the same shift?(Write your answer in the format: 0.xxxx)

An Internet service provider is considering four different servers for purchase. Potentially, the company would be purchasing hundreds of these servers, so it wants to make sure it is making the best decision. Initially, five of each type of server are borrowed, and each is randomly assigned to one of the 20 technicians (all technicians have similar skills). Each server is then put through a series of tasks and rated using a standardized test. The higher the score on the test, the better the performance of the server. The data are shown below. Use the KRUSKAL-WALLIS TEST to determine if the are differences among the servers. Use α = 0.1. 48.5 46.5 52.4 54.1 58.9 56.4 68.2 68.5 64.2 60.1 52.1 64.3 56.3 68.3 48.3 72.2 52.2 70.6 58.4 56.5

Many manufacturers have quality control programs that include inspection of incoming materials for defects. Suppose a computer manufacturer receives computer boards in lots of five. Three boards are selected from each lot randomly for inspection. If we number the boards 1, 2, 3, 4, and 5, a possible random selection is (2, 4, 5). a. List the ten different possible selections. b. Suppose that the boards 1 and 4 are the only defective boards in a lot of five. Three boards are to be chosen at random. Define X as the number of defective boards observed among those inspected. Find the probability distribution (pmf) of X.

An insurance company is thinking about offering discounts on its life insurance policies to nonsmokers. As part of its analysis, the company randomly selects 200 men who are 60 years old and ask them if they smoke at least one pack of cigarettes per day and if they have ever suffered from heart disease. 10 out of the 38 smokers had suffered from some type of heart disease and 12 out of 150 nonsmokers had suffered from some type of heart disease. Can we conclude at the 5% level of significance that smokers have a higher incidence of heart disease than nonsmokers? (Don't hand writing solution)
