Multiple Choice

Use the data given below to answer the following question(s) .
Following is an extract from the database of a construction company.The table shows the height of walls in feet and the cost of raising them.The estimated simple linear regression equation is given as Ŷ = b0 + b1X.(Hint: Use Excel functions) .
$$\begin{array} { | r | r | } \hline \begin{array} { l } \text { Height } \\\text { (ft) }\end{array} & \text { Cost (\$) } \\\hline 4 & 670 \\\hline 3 & 430 \\\hline 7 & 810 \\\hline 9 & 1100 \\\hline 6 & 790 \\\hline 8 & 880 \\\hline 5 & 760 \\\hline 11 & 1200 \\\hline\end{array}$$
-While testing hypotheses for regression coefficients, the t-test for the slope is expressed as:

• A)t = \(\frac { b 1 - 0 } { \text { standard error } }\)
• B)t = \(\frac{b_{1}-0}{b_{0}+b_{1}}\)
• C)t = \(\frac{b_{1}}{b_{0}-b_{1}}\)
• D)t = \(\frac { \text { (standard error) } ^ { 2 } } { b _ { 0 } - b _ { 1 } }\)
