The sum and sum of squares corresponding to length x (in cm) and weight y (in gm) of 50 plant products are given below`sum_(i=1)^(50)x_i=212 ,sum_(i=1)^(50)x_i^2=902. 8 ,sum_(i=1)^(50)y_1=261 ,sum_(i=1)^(50)y_i^2=1457. 6`Which is more varying the length or weight?

Text Solution

Verified by Experts

`sum_(i=1)^(50)x_i=212 ,sum_(i=1)^(50)x_i^2=902. 8 `
Here, `N=50`
Mean `barx_i=(sum_(i=1)^(50)x_i)/N`
`=212/50`
