Question
An environmentalist believes that the two main fact ves that the two main factors that influence a home's heating de temperature and the age of its furnace. She collects data on the homes in January (y), the average outside temperature in degrees Fahrenheit (x1), and the age of the furnace (x2). She estimates the following model ts are the outsi ing cost of 20 cos heat Y = Ako + s,x1 + 2X2 + ;" The results of the regression are: oefficient statistics value tandard Error 9.6 8 17 5.93 1.52 Intercept 27.2 Temperature 4.6 Age 007 148 R2=0.80;Explanation / Answer
13]sample size of heating cost of homes in january = 20
14] the regression equation equation is,
yhat = beta 0 + beta1 x1 + beta2 x2
yhat = 427.2 +(-4.6*30)+(6.1*10)
y hat = 350.2
15]
B] No, because p-value = 0.148> alpha = 0.05.
