14.26 What are the units? How sensitive to changes in water temperature are coral reefs? To find out, measure the growth of corals in aquariums (where growth is the change in weight, in pounds, of the coral before and after the experiment) when the water temperature (in degrees Fahrenheit) is controlled at different levels. In what units are each of the following descriptive statistics measured?
(a) the mean growth of the coral
(b) the standard deviation of the growth of the coral
(c) the correlation between weight gain and temperature
(d) the median growth of the coral
