  • 1. The mean gas mileage for a hybrid car is
    56 miles per gallon. Suppose that the gasoline
    mileage is approximately normally distributed
    with a standard deviation of 3.2 miles per
    gallon.
  • 2. What conditions must n satisfy to make
    the x2 test valid?
  • 1. A random sample of size 15 is selected from a
    normal population. The population standard
    deviation is unknown. Assume the null hypothesis
    indicates a two-tailed test and the researcher
    decided to use the 0.10 significance level. For
    what values of t will the null hypothesis not be
    rejected?

  • How may variance and standard deviation be
    applied to a real-world business-related problem?
    Provide a specific application in which these
    measures are useful.
  • When would you use Chebyshevs theorem and the
    empirical rule in business? How are they
    calculated? Provide one real-life example that
    requires Chebyshevs theorem and one that
    requires the empirical rule.

  • What are some examples of operational definitions
    in research design within your profession? For
    example, in the education field, graduation rate
    and retention rate are important operational
    definitions to measure progress of students.
  • What is the purpose of sampling? What are some
    concerns and dangers of sampling? How important
    is the sample design to data validity? Explain.
    Provide an example where a sample might
    misrepresent data validity. For example, reflect
    on the current political campaign and the
    pollsters!
