`r=(sumdxdy-((sumdx) xx(sumdy))/(N))/(sqrt(sumdx^(2)=((sumdx)^(2))/(N))xx sqrt(sumdy^(2)-((sumdy)^(2))/(N)))`
`=(205-((13)xx(0))/(5))/(sqrt(213-((13)^(2))/(5))xxsqrt(250-((0)^(2))/(5)))`
`=(205-0)/(sqrt(213-33.80)xxsqrt(250-0))`
`=(205)/(sqrt(179.20)xxsqrt(250))=(205)/(13.39xx15.81)`
`=(205)/(211.70)`
`+0.97`
coefficient of Correlation (r)=+0.97.
This is a situation of a high degree of positive correlation.
