A Linear Regression Model Was Fit to Data Collected Over $= - 11.9 + 3.37$

question 24

Multiple Choice

A linear regression model was fit to data collected over a 13 year period
Representing technology adoption over time. Based on the regression output below, the
Durbin Watson statistic indicates
Regression Analysis: Technology Adoption versus Time The regression equation is
Technology Adoption $= - 11.9 + 3.37$ Time

$\begin{array} { l r r r r } \text { Predictor } & \text { Coef } & \text { SE Coef } & \text { T } & \text { P } \\ \text { Constant } & - 11.935 & 3.711 & - 3.22 & 0.008 \\ \text { Time } & 3.3709 & 0.4676 & 7.21 & 0.000 \end{array}$

$S = 6.30783 \quad \mathrm { R } - \mathrm { Sq } = 82.5 \%$

Durbin-Watson statistic $= 0.278634$

• A) that the residuals are positively autocorrelated.
• B) that the residuals are negatively autocorrelated.
• C) that the residuals are not autocorrelated.
• D) that the test is inconclusive.
• E) none of the above; the Durbin Watson cannot be used for this model.

Melting Temperature

The specific temperature at which a solid substance turns into a liquid at atmospheric pressure.

Subducted Plate

A tectonic plate that is being forced underneath another plate into the Earth's mantle at a convergent boundary.

Ophiolite

A portion of the Earth's oceanic crust along with the upper mantle beneath it that has been elevated and is now visible above the surface of the sea.

Oceanic Crust

The part of the Earth's crust that underlies the ocean basins, generally thinner and more dense than continental crust, formed at mid-ocean ridges and recycled into the mantle at subduction zones.
