TABLE 14-6 One of the Most Common Questions of Prospective House Buyers

question 155

Multiple Choice

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
-Referring to Table 14-6,what is your decision and conclusion for the test H₀ : β₂ = 0 vs.H₁ : β₂ ≠ 0 at the α = 0.01 level of significance?

• A)Do not reject H₀ and conclude that the amount of insulation has a linear effect on heating costs.
• B)Reject H₀ and conclude that the amount of insulation does not have a linear effect on heating costs.
• C)Reject H₀ and conclude that the amount of insulation has a linear effect on heating costs.
• D)Do not reject H₀ and conclude that the amount of insulation does not have a linear effect on heating costs.

Definitions:

Mid-Ocean Ridges

Underwater mountain ranges formed by plate tectonics, where new oceanic crust is created by volcanic activity along divergent plate boundaries.

Asthenosphere

The highly viscous, mechanically weak, and ductilely deforming region of the upper mantle of the Earth.

Decompression

The process of reducing pressure in a physical system, often leading to the release of dissolved gases or the formation of bubbles in a liquid.

Solid Mantle

The thick layer of solid rock between the Earth's crust and its liquid outer core, involved in plate tectonics and volcanic activity.
