Suppose that the correlation r between two quantitative variables was found to be r = 0. This means that: (a) there is a strong linear relationship between the two variables. (b) there is no linear relationship between the two variables. (c) there is a strong relationship between the two variables. (d) there is no relationship between the two variables. (e) none of the above.
Determine whether there is a perfect positive linear correlation, a strong positive linear correlation, a perfect negative linear correlation, a strong negative linear correlation, or no linear correlation between the variables. (FIGURE CAN'T COPY)
