6- Hi Wonderful Bartleby Team (Thanks for all the help I do really aprecciate all you guys do) I need help with this exercise from stats. Thanks in advance

 

 

Heights (cm) and weights (kg) are measured for 100 randomly selected adult males, and range from heights of 138 to 192 cm and weights of 40 to 150 kg. Let the predictor variable \( x \) be the first variable given. The 100 paired measurements yield \(\bar{x} = 167.80\) cm, \(\bar{y} = 81.55\) kg, \( r = 0.408 \), \( \text{P-value} = 0.000 \), and \(\hat{y} = -105 + 1.17x\). Find the best predicted value of \(\hat{y}\) (weight) given an adult male who is 156 cm tall. Use a 0.01 significance level.

______________________

The best predicted value of \(\hat{y}\) for an adult male who is 156 cm tall is \(\,\underline{\quad}\,\) kg.

(Round to two decimal places as needed.)
