T F 3. Tests of hypotheses for nominal or ordinal levels of measurement are called nonparametric or distribution-free tests.

T F 4. The chi-square goodness-of-fit test is appropriate for nominal and ordinal levels of data.

T F 5. The chi-square test statistic used in a goodness-of-fit test has n–1 degrees of freedom.

T F 7. There is not one, but a family of chi-square distributions. There is a chi-square distribution for 1 degree of freedom, another for 2 degrees of freedom, another for 3 degrees of freedom, and so on.

T F 9. The shape of the chi-square distribution depends on the size of the sample.

T F 10. The chi-square distribution is positively skewed.

T F 11. In a goodness-of-fit test, the sum o
