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.
