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.

A spinner has four equally sized sectors that are numbered 1, 2, 6, and 6. The spinner is spun twice and the product of the outcomes is found. A fair decision is to be made about which one of four flowers will be planted. The flower options are peonies, roses, asters or petunias. Which description accurately explains how a fair decision can be made in this situation? If the product of the spins is 4, peonies will be planted. If the product is 12, roses will be planted. If the product is 36, asters will be planted. If the product is 1, 2 or 6, petunias will be planted. If the product of the spins is 6, peonies will be planted. If the product is 12, roses will be planted. If the product is 36, asters will be planted. If the product is 1, 2 or 4, petunias will be planted. If the product of the spins is 6, peonies will be planted. If the product is 4, roses will be planted. If the product is 36, asters will be planted. If the product is 1, 2 or 12, petunias will be…

5. An office manager is looking to purchase a new printer for his office. He has narrowed his choices down to four printers but cannot decide which of the four he prefers. He has decided to choose two of the four printers at random, and then to let the other members of the office decide which of the two they prefer. The speeds, in pages per minute, of the four printers are 25, 30, 27, and 32. Considering the speeds of the two printers chosen to be the sample, what are the mean and the standard deviation of the sample mean?
A population of 600 semiconductor wafers contains wafers from three lots. The wafers are categorized by lot and by whether they conform to a thickness specification. The following table presents the number of wafers in each category. A wafer is chosen at random from the population. Nonconforming Conforming Lot A 88 12 165 35
4. A player spins a fair spinner with 3 sections, numbered 0, 2, and 6. Then the player tosses a fair die with four faces, numbered 1, 2, 3, and 4. The player's score is determined by doubling the number on the die, and then subtracting the number on the spinner. What is the average score for this game?
