The bivariate data below give the maximum temperature (denoted by x, in degrees Fahrenheit) and the electricity use (denoted by y, in thousands of kilowatt hours) for a random sample of sixteen summer days. The data are shown in the Figure 1 scatter plot. Also given is the product of the temperature and the electricity use for each of the sixteen days. (These products, written in the column labelled "xy", may aid in calculations.) use, } (in thousands xy (in degrees Fahrenheit) of kilowatt hours) 84.7 361.0 30,576.7 83.7 304.6 25,495.02 375- 74.5 289.0 21,530.5 91.1 314.8 28,678.28 350- 71.0 302.6 21,484.6 325- 92.7 346.5 32,120.55 Electricity use (in thousands of kilowatt hours) 71.1 276.6 19,666.26 275- 80.0 291.1 23,288 250- 93.3 349.6 32,617.68 225- 81.5 259.2 21,124.8 82.9 324.7 26,917.63 97.0 334.5 32,446.5 96.8 290.0 28,072 Temperature (in degrees Fahrenheit) 71.2 227.6 16,205.12 Figure 1 89.9 312.3 28,075.77 98.3 390.9 38.425.47 What is the sample correlation coefficient for these data?
