<u>Use midpoint formula to calculate x or y- coordinates.</u>
- A(x₁, y₁), B(x₂, y₂)
- M = ((x₁ + x₂)/2, (y₁ + y₂)/2)
Answer:
Option (4)
Step-by-step explanation:
Table for the points from the graph attached,
x y xy
2.2 1.8 4.84 3.24 3.96
3.2 1.8 10.24 3.24 5.76
3.6 3 12.96 9 10.8
4.8 3.5 23.04 12.25 16.8
5.2 6.2 27.04 38.44 32.24
6.4 4.5 40.96 20.25 28.8
7.5 7.8 56.25 60.84 58.5
8.5 6.2 72.25 38.44 52.7
n = 8
Formula for the correlation coefficient
r =
r =
r =
r = 0.87
r ≈ 0.9
Therefore, Option (4) is the answer.
