Over a period of one year, a greengrocer sells tomatoes at six different prices (x pence per kilogram). He calculates the average number of kilograms, y, sold per day at each of the six different prices. From these data the following are calculated
\Sigma~x_{i}=200,\Sigma y_{i}=436, \Sigma x_{i}y_{i}=12515. \Sigma{x_{i}}^{2}=7250 \Sigma y_{i}^{2}=39234, n=6.
Estimate the correlation coefficient.
