1. In carrying out a chi-square goodness-of-fit test, what are the "k" and "m" terms in the "df 5 k 2 1 2 m" expression and why is each term present?

2. If a table of expected frequencies differs very little from the frequencies that were observed, would the cal- culated chi-square be large or small? Why?

3. For the null hypothesis, H0: "The data were drawn from a Poisson distribution with A 5 7.0," how many degrees of freedom would be associated with the test if there are 8 cells in the table of frequencies to be analyzed?

4. For the null hypothesis, H0: "The data were drawn from a uniform continuous distribution," how many degrees of freedom would be associated with the test if there are 5 cells in the table of frequencies to be analyzed?
