Recall the relation between degrees Fahrenheit and degrees Celsius

degrees Celsius = 5/9 degrees Fahrenheit 160/9

Let X and Y be the daily high temperature in degrees Fahrenheit for the summer in Los Angeles and San Diego. Let T and S be the same temperatures in degrees Celsius.

Suppose that Cov(X, Y ) = 4 and (X, Y ) = 0.8. Compute Cov(T, S) and (T, S) ((T, S) = correlation)

case study;

Note that it is very unlikely at this point in human evolution that we will sprout wings, a third arm, or purple skin. The survival advantages of such major morphological changes have long been surpassed by applications of human intelligence. Humans can already use their brains to build airplanes. There is therefore no survival advantage we would gain from growing wings. Any disadvantage that humans have because of basic structure has been compensated for by human-made machines. The future of human evolution will therefore most likely involve the brain and the chemical/hormonal systems that support the brain.
