The degrees of freedom equal degrees of freedom for Model F minus degrees of freedom for Model R. A nonsignificant Chi-square indicates that removal of the parameters that are estimated in Model F but not in Model R did not significantly reduce the fit of the model to the data.

Activity overview:
2. As the number of degrees of freedom increases, the distribution becomes less skewed and more symmetric. It appears that the mean equals the number of degrees of freedom. 3. 3.247 and 20.483. 4. about 0.949998; Note that how close this value is to 0.95 depends on how many decimal places are listed in the charts that students use. 5.

The degrees of freedom are always calcu- lated as the number of possible outcomes minus one. Consider the coin flip experiments in Model 1 where you could get heads or tails. How many outcomes were possible in the coin flip experiments? ... If the 2 value falls between two points on the chart, give a range of P values. Coin A = Coin B =
