For 50 randomly selected speed dates, attractiveness ratings by males of their female date partners $(x)$ are recorded along with the attractiveness ratings by females of their male date partners (y); the ratings range from 1 to 10. The 50 paired ratings yield $\bar{x}=6.3, \bar{y)=6.1, r=-0.169, P$-value $=0.240$, and $\hat y)=7.26- 0.185 x$. Find the best predicted value of $\hat{y}$ (attractiveness rating by female of male) for a date in which the attractiveness rating by the male of the female is $x=4$. Use a $0.01$ significance level. The best predicted value of $\hat{y}$ when $x=4$ is (Round to one decimal place as needed.) SP.DL.203
