    Question

    We discuss a linear regression analysis with two predictors. The number of subjects is 12. Calculate the number of degrees of freedom and determine the critical t value needed to establish a 95% confidence interval for a regression coefficient in this model.


    1. TRUE: df = 9; t = 2.262.
    2. FALSE: df = 9; t = 1.833.
    3. FALSE: df = 10; t = 2.228.
    4. FALSE: df = 10; t = 1.812.
