Answer:
Explanation:
Given is a table showing the surface area y in square inches, of a shrinking puddle in x hours
x y
2 25
5 15
8 9
11 2
r -0.993835256
Hence correlation coefficient is option B) -0.99
Part b:
Time Sur area
x y
2 25
5 15
8 9
11 2
r -0.993835256
slope -0.395083406
Intercept 11.53731343
slope =-0.395
Between 5 and 8, slope =

Slope represents the change of y with respect to 1 unit change in x.
Part c:
Yes correlation strong and negative.
