[Mr.Thesaxman]

In the goodness-of-fit chi-square test, the rule of thumb that the expected frequency for each category should be at least 5 exists because:
 a. the chi-square distribution is not symmetrical when the expected frequency of a category is less than 5.
  b. the test statistic for the chi-square distribution is based on the assumption that the expected frequency of each category is greater than 5.
  c. the chi-square distribution is negatively skewed when the expected frequency of a category is less than 5.
  d. the chi-square distribution is continuous while the counts on which the test statistic are based are discrete.
  e. the chi-square distribution is positively skewed when the expected frequency of a category is less than 5.

Which of the following tests do not use the chi-square distribution?
 a. Test of a contingency table
