(y); the ratings range from 1 to 10. The 50 paired ratings yield x = 6.26, = 6.1?, r = - 0.245?, P-value = 0.086?, and y = 7.82 ?0.282x.

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.

here as p vlaue 0.086 is greater than 0.01 level of significance ; tehrefore the correlation is not significant

we can not conlude that there is a linear relationship between x and y

therefore best predicted value of y should be average of Y values which is given by=6.1
