Answer:
Correct option: hire a new statistician .
Step-by-step explanation:
Correlation coefficient is a numerical value used to measure the direction and strength of the linear relationship between two variables.
It is denoted by r. The value of r ranges from -1.00 to +1.00.
A correlation coefficient of -1.00 implies that there is strong negative relationship between two variables.
A correlation coefficient of +1.00 implies that there is strong positive relationship between two variables.
The correlation coefficient between college entrance exam grades and scholastic achievement was found to be r = -1.08.
This correlation value is not possible.
So the university should hire a new statistician.
