The regression coefficients of a bivariate distribution are -0.64 and -0.36 . Then the correlation coefficient of the distribution is

Options

  1. A0.48
  2. B-0.48
  3. C0.50
  4. D-0.50

Correct answer

B. -0.48

Step-by-step solution

Let b₁=-0.64 aligned & b ₂=-0.36 & r = -0.64 -0.36 = 0.48 & ~b ₁ 0 & ~b ₂ 0 & r 0 & r =-0.48 aligned
