Multiple Choice

SCENARIO 13-19
The marketing manager for a nationally franchised lawn service company would like to study the characteristics that differentiate home owners who do and do not have a lawn service.A random sample of 30 home owners located in a suburban area near a large city was selected; 11 did not have a lawn service (code 0) and 19 had a lawn service (code 1) .Additional information available
concerning these 30 home owners includes family income (Income, in thousands of dollars) and lawn size (Lawn Size, in thousands of square feet) .
The PHStat output is given below:
Binary Logistic Regression $$\begin{array}{l}\begin{array} { l r r r r } \hline { \text { Predictor } } & \text { Coefficients } & \text { SE Coef } & { Z } & p \text {-Value } \\\hline \text { Intercept } & - 7.8562 & 3.8224 & - 2.0553 & 0.0398 \\\text { Income } & 0.0304 & 0.0133 & 2.2897 & 0.0220 \\\text { Lawn Size } & 1.2804 & 0.6971 & 1.8368 & 0.0662\\\text { Deviance } & 25.3089\end{array}\\\end{array}$$
-Referring to SCENARIO 13-19, which of the following is the correct interpretation for theLawn Size slope coefficient?

• A)Holding constant the effect of income, the estimated number of lawn services purchased increases by 1.2804 for each increase of one thousand square feet in lawn size.
• B)Holding constant the effect of income, the estimated average number of lawn services purchased increases by 1.2804 for each increase of one thousand square feet in lawn size.
• C)Holding constant the effect of income, the estimated probability of purchasing a lawn service increases by 1.2804 for each increase of one thousand square feet in lawn size.
