True/False

TABLE 14-6
One of the most common questions of prospective house buyers pertains to the cost of heating in dollars (Y).To provide its customers with information on that matter,a large real estate firm used the following 2 variables to predict heating costs: the daily minimum outside temperature in degrees of Fahrenheit (X₁)and the amount of insulation in inches (X₂).Given below is EXCEL output of the regression model. Also SSR (X₁ ∣ X₂)= 8343.3572 and SSR (X₂ ∣ X₁)= 4199.2672
-True or False: Consider a regression in which b₂ = -1.5 and the standard error of this coefficient equals 0.3.To determine whether X₂ is a significant explanatory variable,you would compute an observed t-value of -5.0.
