Question: When adults are asked their weight, the reported weight tends to be less than their actual weight as measured by a scale. Here are the measured weights (in pounds) and the reported weights for 5 women.

(a) What is the explanatory variable?

(b) Find the correlation using the formula. Use statistics mode on your calculator to obtain \[\bar{x},\text{ }{{s}_{x}},\text{ }\bar{y},\text{ }\] and \[\text{ }{{s}_{y}}\]. Do the rest of the calculation by hand (except, of course, for multiplication, addition and division which you can do on your calculator).
