4) The heights of a sample of 10 fathers and their eldest sons are given below (to the nearest cm): Height of father (x) | 170 | 167 | 162 | 163 | 167 | 166 | 169 | 171 | 164 | 165 Height of Son (y) | 168 | 167 | 166 | 166 | 168 | 165 | 168 | 170 | 165 | 168 a) Compute the correlation coefficient. b) Calculate the coefficient of determination and give your comments. [Ans: 0.76; 58%]

Step 1
Mean of fathers' heights = (170+167+162+163+167+166+169+171+164+165)/10 = 166.4 cm Mean of sons' heights = (168+167+166+166+168+165+168+170+165+168)/10 = 167.1 cm Show more…
