Consider the Data Set Shown Below $\begin{array}{c|ccccccc}\mathrm{y} & 0 & 4 & 2 & 3 & 8 & 10 & 11 \\\hline \mathrm{x} & -2 & 0 & 2 & 4 & 6 & 8 & 10\end{array}$

question 89

Short Answer

Consider the data set shown below. Find the rejection region for determining if the Spearman's Rank Correlation between the variables x and y exceeds 0. Use α = 0.025. $\begin{array}{c|ccccccc}\mathrm{y} & 0 & 4 & 2 & 3 & 8 & 10 & 11 \\\hline \mathrm{x} & -2 & 0 & 2 & 4 & 6 & 8 & 10\end{array}$

A) $r > 0.886$
B) $r > 0.714$
C) $r > 0.786$
