Question
Numbers (in thousands) of forest fires over the year and the number (in hundred thousands) of acres burned for 8 recent years are shown. The regression line equation is y’ = 34.921 + 0.489x. The correlation coefficient is r = 0.999. Compute the standard error of the estimate, if appropriate. Assume that a = 0.05 and use a graphing calculator.
Number of fires x 62 69 72 84 45 47 58
Number of acres burned y 65 69 70 76 57 58 63
Compute the standard error of the estimate. Round answer to three decimal places.
Explanation / Answer
y = 65 69 70 76 57 58 63
y' = 65.2390 68.6620 70.1290 75.9970 56.9260 57.9040 63.2830
calculating we get standard error of the estimate
= 0.20099609
=0.201
