# Question

Refer to the previous exercise.

a. The correlation equals -0.890 between x and y, and -0.997 between x and log(y). What does this tell you about which model is more appropriate?

b. The half-life is the time for the weight remaining to be one-half of the original weight. Use the equation = 80.6(0.813)x to predict the half-life of this organic material.
