question 42

Multiple Choice

The data in the table represent the amount of pressure (psi) exerted by a stamping machine (x) , and the amount of scrap brass shavings (in pounds) that are collected from the machine each hour (y) .
Also shown below are the outputs from two different statistical technologies (TI-83/84 Calculator and Excel) . A scatterplot of the data confirms that there is a linear association. Report the equation for predicting scrap brass shavings using words such as scrap, not x and y. State the slope and
Intercept of the prediction equation. Round all calculations to the nearest thousandth. $\begin{array}{|c|r|}\hline x & y \\\hline 2.00 & 2.30 \\\hline 7.80 & 15.14 \\\hline 14.51 & 28.65 \\\hline 2.80 & 4.15 \\\hline 4.01 & 6.35 \\\hline 6.21 & 10.52 \\\hline 11.84 & 24.05 \\\hline 5.11 & 8.75 \\\hline 11.67 & 22.22 \\\hline 8.70 & 17.02 \\\hline\end{array}$
