WebbFinal answer. r = 0.292, P-value = 0.003, and y^ = −105+1.09x. Find the best predicted value of y^ (weight) given an adult male who is 176 cm tall. Use a 0.10 significance level. The best predicted value of y^ for an adult male who is 176 cm tall is kg. (Round to two decimal places as needed.) WebbThis means that when $x=0$ then the predicted value of $y$ is 6.5. The slope is 1.8. For every one unit increase in $x$, the predicted value of $y$ increases by 1.8.
