Question

Fiona called the correlation coefficient to be 0 when observing cell phone production over a 10-year period. She concluded that there is no relationship between the phone production and time. Is Fiona correct? Explain your reasoning.

A. Fiona’s conclusion is correct. If the correlation coefficient is 0, there is a linear regression.

B. Fiona’s conclusion is not correct. If the correlation coefficient is less than 1, there is not a linear relationship, but could be another type of relationship.

C. Fiona’s conclusion is not correct. If the correlation coefficient is 0, there is not a linear relationship, but could be another type of relationship.

D. Fiona’s conclusion is correct. If the correlation coefficient is less than 1, there is not a linear relationship, but could be another type of relationship.

Answer 1

C

Explanation:

When the correlation coefficient is 0 (ranges from 0-1) this means that there is no direct linear correlation between two variables. When Fiona knows that it is 0, it means it is not linear correlation between.
