Question: In order to know how much solar panels might help, a family records their consumption of natural gas before the panels are installed. (Gas consumption is higher in cold weather). The data for 16 consecutive months are below. Outside temperature is recorded in degree-days, a common measure of demand for heating. A day’s degree-days are the number of degrees its average temperature falls below 65 degrees Fahrenheit. Gas used is recorded in hundreds of cubic feet. Make a plot and describe the pattern. Is correlation a reasonable way to describe the pattern? What is the correlation? (It is suggested that SPSS be used for this problem)
