x and y are the arithmetic means of the runs of two batsmen A and B in 10 innings respectively and _ A , _ B are the standard deviations of their runs in them. If batsman A is more consistent than B , then he is also a higher run scorer only when

Options

  1. A0 _A _B x y ; x y 1
  2. Bx y _A _B 1
  3. Cx y _A _B 1
  4. Dx y 1 ; 1 x y _A _B

Correct answer

A. 0 _A _B x y ; x y 1

Step-by-step solution

Batsman A is more consistent than B Coefficient of variation of A coefficient of variation B _A x _B y 0 _A _B x y A scores higher runs x_ i A x_ i B x y x y 1
