In a recent study, the weight of an orange (x, in pounds) was compared with the amount of fresh-squeezed juice from the orange (y, in ounces). A random sample of n = 15 oranges was obtained. Each was carefully weighed and squeezed. The following summary statistics were obtained.

Permafrost is soil or rock that remains at or below 0°C for at least two years. Suppose an Arctic study analyzed the observed changes in mean annual air temperature and the depth of the freezing layer. The depth of the upper surface of the permafrost layer (y, in feet) was measured for n = 26 mean annual air temperatures (x, in °F). The summary statistics are given below.
