Which of the following correlation coefficients would represent the weakest correlation?
A) -0.97
B) 0.87
C) 0.02
D) -0.5

Explanation:

Any r values close to -1 or +1 represent strong correlation. Specifically, anything close to r = -1 is strong negative correlation, while anything close to r = 1 is strong positive correlation.

As you move closer to r = 0, the correlation weakens. The value r = 0.02 in choice C is the closest to r = 0, so this correlation is the weakest among the group of other r values.

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
