Prоblem-Sоlving Questiоn 1: Tаil-feаther length in birds is sometimes а sexually dimorphic trait. That is, the trait differs substantially for males and for females. Researchers studied the relationship between weight (x) and tail-feather length (y) in a sample of 5 wild male longtailed finches. Here are the data: r = correlation between x and y = 0.89 = mean of the values of x = 17.64 = mean of the values of y = 75.20 sx = standard deviation of the values of x = 2.22 sy = standard deviation of the values of y = 7.05 (a) [10 points] Obtain the equation for the least-squares regression line modeling the average tail-feather length (y) as a function of the average weight (x) for the wild male longtailed finches. Write down the least-square regression line. [Need to show in detail.] (b) [2 points] What is the meaning of the slope in the context of this problem? Please describe the slope in a statement. (c) [4 points] What percent of the variation in the average tail-feather length (y) is explained by the least-squares regression model? (d) [4 points] Use the regression equation to predict the tail-feather length of a male longtailed finch weighing 30g. Does this value make any sense? Please justify.
