Heights (cm) and weights (kg) are measured for 100 randomly selected adult males, and range from heights of 136 to 189 cm and weights of 38 to 150 kg. Let the predictor variable x be the first variable given. The 100 paired measurements yieldx=167.85 cm, y=81.51 kg, r=0.249, P-value=0.012, and y=-103+1.17x Find the best predicted value of (weight) given an adult male who is 178 cm tall. Use a 0.10 significance level The best predicted value of y for an adult male who is 178 cm tall is kg. (Round to two decimal places as needed.) CUS

The data show the chest size and weight of several bears. Find the regression equation, letting chest size be the independent (x) variable. Then find the best predicted weight of a bear with a chest size of 48 inches. Is the result close to the actual weight of 318 pounds? Use a significance level of 0.05.
