Report ...On the next page we give the average hourly outdoor temperature (x) in a city during a week and the city’s natural gas consumption (y) during the week for each of eight weeks (the temperature readings are expressed in ...Consider testing H0: β1 = 0 versus Ha: β1 = 0. Figure tells us that t = 30.5802 and that the related p-value is less than .001. Assuming that the bivariate normal probability distribution assumption holds, test H0: ρ = 0 ...The residuals given by the service time prediction equation y-bar = 11.4641 + 24.6022x are listed in Table 13.7(a). a.
