Section 13.5 Homework Hints

    Problems 1-2
    Look in the book to find a statement of each of these properties.
    Problems 3-10
    Use the binomial distribution theorem as shown in Example 1.
    Problems 11-16
    Use the binomial distribution theorem. See the discussion following the box for binomial experiments.
    Problems 17-18
    See Example 1b to see how to handle inequalities like these problems.
    Problems 19-22
    See Example 1.
    Problems 23-26
    Use the binomial distribution theorem where p is the probability of drawing a red pen and k is the number of people selecting that color.
    Problems 27-32
    Let p = 0.9 and let k represent the number of white-faced calves, and then use the binomial probabilities.
    Problems 33-37
    Let p = 0.2 and let k represent the number of infected leaves, and then use the binomial probabilities.
    Problem 38
    You need to work Problems 33-37 to answer this question.
    Problems 39-52
    These applications use the binomial distribution theorem. Look at Examples 3 and 4 for some help on how to set up these problems.

    Note: Homework Hints are given only for the Level 1 and Level 2 problems.

    However, as you go through the book be sure you look at all the examples in the text. If you need hints for the Level 3 problems, check some sources for help on the internet (see the LINKS for that particular section. As a last resort, you can call the author at (707) 829-0606.

    On the other hand, the problems designated "Problem Solving" generally require techniques that do not have textbook examples.

    There are many sources for homework help on the internet.
