Heights​ (cm) and weights​ (kg) are measured for 100 randomly selected adult​ males, and range from heights of 135 to190 cm and weights of 39 to150kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield x̄ =167.89 ​cm, ȳ = 81.55​kg, r=0.414​, ​P- value=0.000​, and ŷ =−103+1.04x. Find the best predicted value of ŷ ​(weight) given an adult male who is184 cm tall. Use a 0.05 significance level.   The best predicted value of ŷ for an adult male who is 184 cm tall is ___kg.
