Answer:
Step-by-step explanation:
We must write the function of the line in the form
First calculate the slope m
Then
To have b replaced a point in the function
Finally the function is
The correlation coefficient for the data in the table is A. –0.993
<h3>Calculations and Parameters:</h3>Using this formula:
We would use x and y to represent the unknowns.
n = 4
We have,
- ∑x = 42,
- ∑y = 44.37 ,
- ∑xy = 461.3
- ∑x^2 = 446,
- ∑y^2 = 494
Putting these values in the formula would bring the answer as. A. –0.993
