For a linear regression equation, the sum of the squared residuals can be computed directly by finding the difference between each Y and its predicted Y, then squaring the difference and adding the squared values. An alternative procedure is to calculate ____.
A) r2SSY
B) (1 - r2)SSY
C) (1 + r2)SSY
D) SSY/SSX
Question 2
What is the relationship between the alpha level, the size of the critical region, and the risk of a Type I error?
A) As the alpha level increases, the size of the critical region increases and the risk of a Type I error increases.
B) As the alpha level increases, the size of the critical region increases and the risk of a Type I error decreases.
C) As the alpha level increases, the size of the critical region decreases and the risk of a Type I error increases.
D) As the alpha level increases, the size of the critical region decreases and the risk of a Type I error decreases.
