question 67

Short Answer

Write the word or phrase that best completes each statement or answers the question.
-To investigate the relationship between yield of potatoes, $\mathrm { y }$ , and level of fertilizer application, $x$ , an experimenter divides a field into eight plots of equal size and applies differing amounts of fertilizer to each. The yield of potatoes (in pounds) and the fertilizer application (in pounds) are recorded for each plot. The data are as follows:
$\begin{array}{l|cccccccc}\mathrm{x} & 1 & 1.5 & 2 & 2.5 & 3 & 3.5 & 4 & 4.5 \\\hline \mathrm{y} & 25 & 31 & 27 & 28 & 36 & 35 & 32 & 34\end{array}$

Summary statistics yield SSxx $= 10.5 , \mathrm { SSyy } = 112$ , and SSxy $= 25$ . Calculate the coefficient of determination.
