1 Which of the following is NOT a method of assessing aregression model?

A. Doing an F-test for the overall validity of the model B.Doing an F-test for the ratio of variances C. Observing theR-squared value D. Doing a t-test for slopes

2 The degrees of freedom for the F-test in overall modelvalidity are k and n-k-1, with k being the number of independentvariables in the model. A: True B: False 3 The degrees of freedom for the t-test for slope is n-k. A: True B: False 4 When the correlation coefficient is zero, then there is norelationship between the dependent variable and the independentvariable A:True B:False
