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=6.0​, r=−0.228​, ​P-value=0.111​, and y=7.81−0.280x. 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=5. Use a 0.10 significance level. The best predicted value of ywhen x=5 is nothing. ​(Round to one decimal place as​ needed.)
