Prоblem-sоlvingQuestiоn 2: Becаuse elderly people mаy hаve difficulty standing straight to have their heights measured, a study looked at predicting overall height from height to the knee. The data, in centimeters (cm), for five elderly men are listed in the table.r = correlation between x and y = 0.877 = mean of the values of x = 49.72 = mean of the values of y = 164.72sx = standard deviation of the values of x = 6.36sy = standard deviation of the values of y = 17.6Use your calculator. What is the equation of the least‑squares regression line for predicting height from knee height? (Enter the coefficients rounded to one decimal place.)(a) [10 points] Write down the least-square regression line. (Need to show in details.)(b) [2 points] What is the meaning of the slope in the context of this problem? Please describe the slope in a statement.
