Choosing which types of Distribution

Tags:
  1. Nov 4, 2012 #1
    Given the following distributions I have to choose which one to use under the given scenario.

    Distributions
    - Binomial
    - Poisson
    - Pascal
    - Multinomial
    - Hypergeometric
    - Normal (z distribution)


    Scenarios:
    a. I love snickers so I pull candy from the bag and immediately putting the candy
    back in the bag until I have pulled out a snickers 6 times.
    b. To check to see if all of my students are following along and learning at a
    reasonable rate, I compare the variance of my classes’ exam grades against the
    population variance of exam grades in statistics.
    c. If I want to pull candy out of the bag and immediately put the candy back in the
    back after observing what type of candy was pulled out. Assume the bag of candy
    has snickers, kit-kats, and milky ways in it.
    d. To check to see if all of my students are following along and learning at a
    reasonable rate relative to other stats classes, I compare the variance of my
    classes’ exam grades against another stats classes’ exams grades.
    e. Flipping a coin until it lands on heads once.
    f. Recording the number of car accidents on campus before noon.
    g. Playing poker at a casino where every card dealt is observed and recorded.
    Assume that you are dealing without replacement.
    h. Rolling a die 100 times in order to see how many times the die lands on one.
