Question
Which of the following is(are) TRUE if the coefficient of determination between the response and the predictor
variables is 0.81 based on a random sample of size n.
O B. The Pearson's sample correlation coefficient is +0.9.
O A. This means that 19% of the total variation in the response variable remains unexplained by the simple linear regression
model that uses the given predictor variable.
O Both A and B
Neither A nor B

A study on the efficient utilization of operating rooms was conducted. Results showed that induction and
emergence from anesthesia last for 40 minutes. Also, 1.33 minutes is being added to the total operating
procedure time (TPT) in minutes for every additional estimated surgical control time (SCT).
Which of the following is(are) TRUE about the simple linear regression model to describe the relationship
between TPT and SCT?
1- TPT is the dependent variable.
Il - SCT is the independent variable.
O Neither I nor II
O Both I and II
O II Only
I only
