John took a test that required him to rank order the importance of 15 items to help him survive in the desert.The following table shows his results along with the correct order.
$$\begin{array} { | c | c | c | }
\hline \text { Item } & \text { Inhn's Order } & \text { Correct Order } \
\hline 1 & 1 & 4 \
\hline 2 & 11 & 9 \
\hline 3 & 5 & 3 \
\hline 4 & 12 & 15 \
\hline 5 & 6 & 12 \
\hline 6 & 10 & 5 \
\hline 7 & 3 & 1 \
\hline 8 & 15 & 10 \
\hline 9 & 8 & 14 \
\hline 10 & 9 & 7 \

\hline 13 & 13 & 13 \
\hline 14 & 2 & 6 \
\hline 15 & 7 & 8 \
\hline
\end{array}$$ Calculate and interpret the Spearman coefficient of rank correlation and use the 0.01 level of significance in testing whether its true value could be something other than 0.
