Multiple Choice

SCENARIO 12-13
In this era of tough economic conditions, voters increasingly ask the question: "Is the educational achievement level of students dependent on the amount of money the state in which they reside spends on education?" The partial computer output below is the result of using spending per student ($) as the independent variable and composite score which is the sum of the math, science and reading scores as the dependent variable on 35 states that participated in a study.The table includes only partial results. $$\begin{array}{l}\begin{array} { l c } \hline { \text { Regression Statistics } } \\\hline \text { Multiple R } & 0.3122 \\\text { R Square } & 0.0975 \\\text { Adjusted R } & 0.0701 \\\text { Square } & \\\text { Standard } & 26.9122 \\\text { Error } & \\\text { Observations } & 35 \\\hline\end{array}\\\end{array}$$
ANOVA
$\begin{array}{lccc}& d f & S S & M S & F \\\text { Regression } & 1 & 2581.5759 & \\\text { Residual } & & & 724.2674 \\\text { Total } & 34 & 26482.4000 &\end{array}$
$$\begin{array}{l}\begin{array} { l c c c c } \hline & \text { Coefficients } & \text { Standard Error } & t \text { Stat } & P \text {-value } \\\hline \text { Intercept } & 595.540251 & 22.115176 & & \\\text { Spending per } & & & & \\\text { Student(\$) } & 0.007996 & 0.004235 & \\\hline\end{array}\end{array}$$
-Referring to Scenario 12-13, the conclusion on the test of whether composite score depends linearly on spending per student using a 10% level of significance is

• A)There is not enough evidence that composite score does not depend linearly on spending per student.
• B)There is enough evidence that composite score does not depend linearly on spending per student.
• C)There is not enough evidence that composite score depends linearly on spending per student.
• D)There is enough evidence that composite score depends linearly on spending per student.

Definitions:

Revenue

Revenue is the total amount of money received by a company for goods sold or services provided during a certain period of time.

Pairs

Objects considered together because of their relationship or similarity, often used in the context of programming or data analysis.

Students

Individuals engaged in learning, either in formal educational institutions or through informal means, focused on acquiring knowledge or skills.

Zero Net Difference

When the difference between expense and revenue equals zero; meaning that the values of both are equal; also called breakeven points when revenue and expenses are graphed on the same coordinate plane.
