A study was conducted to identify the predictors for symptomatic distress in EMS workers. Five predictor variables were used in a regression model and fitted to a data collected on n = 147 EMS workers and yielded F* = 34.47. In testing the usefulness of this model, the null hypothesis (H0 : Model is not useful) can be rejected (at = 0.05) if F* = 34.47 is greater than a critical value (that you find using the F-table). What are the degrees of freedom for finding this critical value in the F-table?
