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 x=6.3​, y=5.9​, r=−0.256​, ​P-value=0.073​, and y=7.73−0.285x. Find the best predicted value of y ​(attractiveness rating by female of​ male) for a date in which the attractiveness rating by the male of the female is x=6. Use a 0.01 significance level. The best predicted value of y when x=6 is?
