Example 4. In a partially destroyed laboratory record of an analysis of a correlation data, the following results only are legible: Variance of x = 9 Regression equations: 8x - 10y +66 = 0, 40x - 18y = 214. What were (a) the mean values of x and y (b) the standard deviation of y and the co-efficient of correlation between x and y? Example 4.
