  Indicate whether the statement is true or false

Q. 2

Which of the following correctly describes experiments?
 a. They are two random events, A and B, such that the probability of one event is not affected by the occurrence of the other event; therefore, P(A) = P(AB).
  b. They are different events that have no outcomes in common.
  c. They are activities that result in one and only one of several clearly defined possible outcomes and that do not allow us to tell in advance which of these will prevail in any particular instance.
  d. All of the above.
  e. None of these.

Q. 3

  Indicate whether the statement is true or false

Q. 4

A useful graphical method of displaying the sample space for an experiment is:
 a. a tree diagram
  b. a box plot
  c. a histogram
  d. a scatterplot
  e. a barplot

Q. 5

The observed frequency of a cell should not be allowed to be smaller than 5 when a chi-square test of homogeneity is being conducted.
  Indicate whether the statement is true or false

Q. 6

The set of all simple events of an experiment is called:
 a. a compound event
  b. a sample space
  c. a population
  d. a random sample
  e. all of these

Q. 7
