r = (Σxy)/N(SDx)(SDy)
Calculate each term and solve.
We do not do your work for you.
X 3, 5, 6, 8, 9, 10, 12, 14, 15
Y 30,33,34,36,37,40, 50, 60, 70
Calculate Linear Correlation Coefficient r
Use significance level 0.05 and Appendix Table A-6 to make decision
about linear correlation between x and y.
