BUS 308 Course Tutorial
  • BUS 308 Week 1 DQ 1 Performance Report
  • BUS 308 Week 1 DQ 2 The Empirical Rule vs.
    Chebyshev
  • You are the manager at a company and are asked to
    present a report on the year-to-date performance
    of your division. What type of statistical
    information would you include in your report? In
    particular, which descriptive statistics (mean,
    median, standard deviation, etc.) do you think
    would best represent the main aspects of the
    performance of your division? What types of
    graphical presentation
  • The Empirical Rule vs. Chebyshevs
    TheoremDiscuss how the Empirical Rule works and
    how it relates to the bell curve as illustrated
    in Figure 3.14 (a). Then, explain Chebyshevs
    Theorem and how it is different from the
    Empirical Rule. Give a specific example of a
    population with which the Empirical Rule might be
    most effective

    variables are
  • 2. Question As a general rule, when creating a
    stem-and-leaf display, there should be between
    ______ stem values.
  • 3. Question The median is the value below
    which and above which approximately 50 percent of
    the measurements lie.

BUS 308 Course Tutorial
  • BUS 308 Week 2 DQ 1 Relative Frequency
  • BUS 308 Week 2 DQ 2 Applications for Probability
  • Relative Frequency. Conceptually we would expect
    the probability of newborn males and females to
    be the same. However, census reports indicate
    that the ratios of males and females in various
    countries do not conform to the theoretical
    prediction. What do you think accounts for this
    variation? Can you think of other cases where the
    expected probabilities do not quite agree with
    the empirical values?
  • Applications for Probability. In what situations
    might you use probability as a manager to
    approach business-related problems? What are the
    advantages to using probability concepts in
    business decisions? Are there any disadvantages
    or possible pitfalls to avoid in using
    probability in business?

  • BUS 308 Week 3 Assignments Problems 7.11, 7.30,
    8.8, 8.38
  • 1. Question In a statistical study, the random
    variable X 1, if the house is colonial, and X
    0 if the house is not colonial, then it can be
    stated that the random variable is continuous.
  • 2. Question The set of all possible
    experimental outcomes is called a(n)

BUS 308 Course Tutorial
  • BUS 308 Week 3 DQ 1 Unscientific Sampling
  • BUS 308 Week 3 DQ 2 Article Review
  • Unscientific Sampling. Consider question 7.45
    from the text A Milwaukee television station,
    WITI-TV, conducted a telephone call-in survey
    asking whether viewers liked the new newspaper,
    the Journal Sentinel. On April 26, 1995, Tim
    Cuprisin, a columnist for the Journal Sentinel,
    wrote the following comment WITI-TV (Channel 6)
    did one of those pollswhich they admit are
    unscientific
  • Article Review. Many articles present statistical
    data and list margins of error (for example,
    reports on political opinion polls, growth or
    decline of the housing markets, manufacturing
    sectors, etc.). Find one such article from a
    reliable source (such as EBSCO or Proquest) in
    the online library that includes a construction
    of confidence intervals for the data studied, and
    give a summary of the topic and the statistical

  • BUS 308 Week 3 Quiz (10 MCQ)
  • BUS 308 Week 4 Assignments Problems 9.13, 9.22,
    12.10, 12.18(a)
  • Question There is little difference between the
    values of ta/2 and Za/2 when the sample
  • 2. Question If the population proportion is .4
    with a sample size of 20, then is this sample
    large enough so that the sampling distribution of
    is a normal distribution.

BUS 308 Course Tutorial
  • BUS 308 Week 4 DQ 1 Hypothesis Test
  • BUS 308 Week 4 DQ 2 Creating Hypotheses
  • Give an example of a hypothesis test you could
    perform at work or at home. State what the Null
    and the Alternative hypotheses would be in your
    test. Explain how you would settle on a
    reasonable level of significance for your
    scenario. Also explain what the type I and II
    errors would be if you reached the incorrect
    conclusion in your test.
  • Creating Hypotheses. Assume you are the manager
    of a paint manufacturing factory. Your company
    has received complaints from customers that the
    containers hold less than the amount printed on
    them. On the other hand, corporate management is
    concerned that the containers hold more than the
    standard amount. You assign a statistician to
    verify these claims.

  • BUS 308 Week 4 Quiz (10 MCQ)
  • BUS 308 Week 5 DQ 1 Linear Correlation
  • 1. Question Consider using p-value to test H0
    versus Ha by setting a equal to .10. We reject H0
    at level a of significance if and only if the
    p-value is
  • 2. Question When carrying out a sample test
    (with ó known) of H0 µ 10 vs. Ha µ gt 10 by
    using a rejection point, we reject Ho at level of
    significance a if and only if the calculated test
    statistic is
  • Linear Correlation. Do you think there is a
    correlation between CEO salaries and the degree
    of success of a company? If you were to take a
    sample of companies with comparable size, market
    capitalization, and product category, and plot
    CEO salaries against the net profit of their
    respective companies, do you expect to find a
    linear correlation between the two? Explain

11
BUS 308 Course Tutorial
  • BUS 308 Week 5 DQ 2 Quality Control
  • BUS 308 Week 5 Final Part I - Excel
  • Quality Control. Visit the websites on Quality
    Control (QC) listed in the Required Websites for
    this week. In addition, locate an article on the
    Internet or in the Library databases that
    describes an example of the use of statistics in
    Quality Control. In your post, briefly define
    Quality Control and explain its importance. Also,
    describe some of the most widely used tools
  • Calculate the mean yearly value using the average
    gas prices by month found in the"Final Project
    Data Set".
  • 2.Using the years as your x-axis and the annual
    mean as your y-axis, create a scatterplotand a
    linear regression line.
  • 3.Answer the following questions using your
    scatterplot and linear regression line What is
    the slope of the linear regression line? What is
    the Y-intercept of the linear regression line?

BUS 308 Course Tutorial
  • BUS 308 Week 5 Final Part II Analysis Paper on
    gas prices
  • Imagine that you are a manager at a delivery
    service and you are creating a report toproject
    the effects on your company of rising gas prices
    in the next ten years.
  • Using thepreceding statistical analysis as your
    basis and outside scholarly resources to support
    yourclaims,
  • write a 3 to 5 page paper interpreting the
    results from this perspective. Include
    thefollowing considerations
