For the following pair of variables, state the units that might be used to measure each variable. Then state whether you believe that the two variables are correlated. If you believe they are correlated, state whether the comrelation is positive or negative. Explain your reasoning. The heights and weights of 50 randomly selected females between the ages of 1 and 21 To measure height, the unit might be used. To measure weight, the unit might be used. What correlation, if any, is there between the variables?
A. There is a positive correlation because women's weight tend to increase when height decreases
B. There is a negative correlation because women's weight tend to increase when height decreases.
C. There is a positive correlation because women's weight tend to increase when height increases
D. There is a negative correlation because women's weight tend to increase when height increases.
E. The variables are not correlated.
