Consider 10 observations x_1,x_2,\ldots,x_10 such that \displaystyle ∑_i=1^10(x_i-α)=2 and \displaystyle ∑_i=1^10(x_i-β)^2=40, where α,β are positive integers. Let the mean and the variance of the observations be \dfrac65 and \dfrac8425 respectively. Then \dfracβα is equal to: | Watch the step-by-step video solution for this NIMCET PYQ.
