Example 18 - Yola

A student calculates the value of r as 0.7, when the value of n is 5 and he concludes that r is highly significant. Does he correct? Calculate the limits for population correlation coefficient. If the calculated value of PE (r) = 0.085 for r = 0.7 find the value of n. Solution . We have, r = 0.7, n = 5 . PE (r) = 0.6745 = 0.6745 × = 0.154 ................
