| 22 or 23 (18 complete) This Test 23 pls pos Heights (cm) and weights (kg) are measured for 100 randomly selected adult males, and range from heights of 136 to 193 cm and weights of 41 to 150 kg Let the predictor vanable x be the first variable given The 100 pared measurements yeld x= 168 21 cm, y-81 64 kg. 0 156, Pvalue-o 121, and y-101+ 1.06x. Find the best predicted value of y (weight) given an adult male who is 155 cm tall Use a 0.01 significance lewel The best predicted value of y for an adult male who is 155 cm tall is kg Round to two decimal places as needed.) Enter your answer in the answer box Activity Details

Explanation / Answer

Since p - value is greater than 0.01, we do not reject Ho and hence, we can't conclude that the model is useful in predictin the weight.

Hence,

Best predicted value = Mean of y = 81.64 kg
