Question: Five observations taken for two variables follow. x i 4 6 12 6 13 y i 40 50 30 50 20 Compute the sample covariance

Five observations taken for two variables follow.

xi 4 6 12 6 13
yi 40 50 30 50 20

  1. Compute the sample covariance (to 1 decimal place). If your answer is negative, enter 'minus' sign e.g. -300.
  2. Compute the sample correlation coefficient (to 3 decimals). If your answer is negative, enter 'minus' sign e.g. -300.
