Math Problem Statement
Twenty different statistics students are randomly selected. For each of them, their body temperature (degreesC) is measured and their head circumference (cm) is measured. If it is found that requals0, does that indicate that there is no association betwen these two variables? Question content area bottom Part 1 Choose the correct answer below. A. Yes, because if requals0, the variables are completely unrelated. B. No, because r does not measure the strength of the relationship, only its direction. C. No, because if requals0, the variables are in a perfect linear relationship. D. No, because while there is no linear correlation, there may be a relationship that is not linear.
