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?
