Put the top point on the first point from the top and the other one on the first point from the bottom.
2n + 20 = -2
20 + 2 = -2n
22 = -2n
22/2 = n
11 = n
Answer:
0.50
Step-by-step explanation:
we know that
Observing the graph
we have the following points
(1,3),(2,4),(3,9),(4,7),(5,2),(6,18)
Using a Excel tool (Correl function)
The correlation coefficient is equal to r=0.605639
see the attached table
therefore
The correlation coefficient that best matches the data plotted on the graph is 0.50
