  • BUS 308 Week 1 DQ 1 Performance Report (Ash
    Course)
  • BUS 308 Week 1 DQ 2 Probability
  • 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 (histogram, dot plot,
    stem-and-leaf, bar chart, etc.) would you
    include? Explain your reasoning
  •  
  • Things vary in life virtually nothing (except
    physical standards such as the speed of light) we
    interact with is constant over time.
  • Much of this variation follows somewhat
    predictable patterns that can be examined using
    probability.
  • An example of a subjective probability is Cops
    usually do not patrol this road, so I can get
    away with speeding.
  • An empirical probability example is Each
    production run has a 5 reject rate.

  • BUS 308 Week 1 DQ 2 The Empirical Rule vs.
    Chebyshev Theorem (Ash Course)
  • BUS 308 Week 1 Problem Set
  • 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 and one with which Chebyshevs
    Theorem might be most effective. Respond to at
    least two of your classmates postings.
  • 1. For assistance with these calculations, see
    the Recommended Resources for Week One.
    Measurement issues.
  • Data, even numerically code variables, can be one
    of 4 levels nominal, ordinal, interval, or
    ratio.
  • It is important to identify which level a
    variable is, as this impacts the kind of analysis
    we can do with the data.

  • BUS 308 Week 2 DQ 1 Hypotheses
  • BUS 308 Week 2 DQ 1 Relative Frequency (Ash
    Course)
  • Discussion 2-1/Hypotheses
  • What is a hypothesis test? Why do we need to use
    them to make decisions about relating sample
    results to the population
  • why cant we just make our decisions by the
    sample value?
  • 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?

  • BUS 308 Week 2 DQ 2 Applications for Probability
    (Ash Course)
  • BUS 308 Week 2 DQ 2 Variation
  • 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?
  • Variation exists in virtually all parts of our
    lives.
  • We often see variation in results in what we
    spend (utility costs each month, food costs,
    business supplies, etc.).
  • Consider the measures and data you use (in either
    your personal or job activities).
  • When are differences (between one time period and
    another, between different production lines,
    etc.) between average or actual results
    important?

    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

    results presented.

    the results better? Why?
  • 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

    in producing outcomes.
  • What are some examples of variables that you
    might want to check using the chi-square tests?
    What would these results tell you?
  • 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
