  5. BUS 308 Week 1 DQ 1 Performance Report (Ash Course) FOR MORE CLASSES VISIT www.bus308outlet.com 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

  6. BUS 308 Week 1 DQ 2 Probability FOR MORE CLASSES VISIT www.bus308outlet.com 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.

  7. BUS 308 Week 1 DQ 2 The Empirical Rule vs. Chebyshev Theorem (Ash Course) FOR MORE CLASSES VISIT www.bus308outlet.com The Empirical Rule vs. Chebyshev’s TheoremDiscuss how the Empirical Rule works and how it relates to the bell curve as illustrated in Figure 3.14 (a). Then, explain Chebyshev’s 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 Chebyshev’s Theorem might be most effective. Respond to at least two of your classmates’ postings.

  8. BUS 308 Week 1 Problem Set FOR MORE CLASSES VISIT www.bus308outlet.com 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.

  12. BUS 308 Week 2 DQ 1 Hypotheses FOR MORE CLASSES VISIT www.bus308outlet.com 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 can’t we just make our decisions by the sample value?

  13. BUS 308 Week 2 DQ 1 Relative Frequency (Ash Course) FOR MORE CLASSES VISIT www.bus308outlet.com 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?
