Section 14.2 Homework Hints

    Problems 1-9
    There are many problems throughout the text labeled IN YOUR OWN WORDS. Just relax; do not be afraid to give your opinion. For the most part, these questions do not have "right" or "wrong" answers. You should spend about five minutes in answering each of these questions.
    Problems 10-11
    These problems are included to test your understanding of the terms standard deviation and variance.
    Problems 12-21
    As you are working these problems pay attention to the differences amoung the mean, median, and mode. See Example 1 for some help working these problems.
    Problems 22-31
    See Example 4 for the range and Example 6 for the standard deviation. It would be helpful to have a calculator when working these problems.
    Problem 32
    Look for a pattern to answer this question.
    Problem 33
    Find the quautiles by first finding the meadian, and then the other two quartile markers. Use these value to draw the box plot as shown in Example 5.
    Problems 34-36
    See Example 3.
    Problems 37-38
    See Example 3 for the mean, median, and mode, and Example 4 for the range.
    Problems 39
    See Example 3.
    Problem 40
    See Example 1.
    Problems 41-44
    Begin by finding the mean, median, and mode, and then answer the questions asked. Next, look at your answer and look at the graph. Can you deduce the answers to the questions without actually calculating the mean, meadian, and mode. You should look at Example 2 to help you with this reasoning.
    Problem 45
    It will help if you use a calculator for this problem. See Example 1.
    Problem 46
    a. Use the definition of quartiles.
    b. See Example 5.
    c. See Example 6.
    Problems 47-52
    See Example 6; you will need a calculator to work these problems.
    Problem 53
    See Example 1 for the mean, median, and mode; Example 4 for the range; and Example 6 for the standard deviation.
    Problems 54-55
    You will need a pair of dice to work these problems. Roll the dice to gather the data for them. Use Example 1 for the mean, median, and mode; Example 4 for the range; and Example 6 for the standard deviation. Answers will vary each time you perform this experiment.
    Problem 56

    Use the definition of percentile to answer this question.
