A placement test is required for students desiring to take a finite mathematics course at a university. The instructor of the course studies the relationship between students' placement test score and final course score. A random sample of eight students yields the following data. $$\begin{array}{l}
\text { Placement Score}&\text { Final Course Score }\
\hline 38 & 63 \
90 & 41 \
95 &54 \
51 & 32 \
86 & 93 \
74 & 60 \
60 & 61 \
57 & 89
\end{array}$$ Compute the rank correlation coefficient, rs, of the data and test the claim of no correlation between placement score and final course score. Use a significance level of 0.05.
