Answer
A.Randolph’s conclusion is not correct. If the correlation coefficient is 0, there is not a linear relationship, but there could be another type of relationship.
Step-by-step explanation
A value of 0 for a correlation coefficient would mean there is no association between the two variables in the test. A value greater than zero would mean a positive correlation when a rise in the values of one variable mean a rise in the value of the other variable.
