Question

find the probableError if our is equal to0.6 and N is equal to64Write interpretation

Answer 1

Answer:

Here, we have to calculate the probable error. Given, r = 0.7 and n = 64. We know that,

P. E. = 0.674 × {(1-r2 )/√N}

= 0.6745 × {(1 – (0.7)2 )/√64}

= 0.6745 × 0.06375

≈ 0.043

Therefore, the P.E. is 0.043. Now, we have to calculate the limits of the population correlation coefficient. We use the formula,

Probable Limit- ρ (rho) = r ± P.E.r

Hence, we get, (0.7 ± 0.043) i.e. (0.743, 0.657).
