Short Answer Question We have a dataset with n= 10 pairs of observations (li, Yi), and n Σ X; = 683, Yi = 813, i=1 i=1 n n { x = 47,405, Xiyi = 56,089, y = 66, 731. i=1 i=1 i=1 What is the line of best fit for this data?
Fitting a straight line to a set of data yields the following prediction line. Complete (a) through (c) below. =8+7X a. Interpret the meaning of the Y-intercept, bo. Choose the correct answer below. O A. The Y-intercept, bo 7, implies that when the value of X is 0, the mean value of Y is 7. O B. The Y-intercept, bo 8, implies that for each increase of 1 unit in X, the value of Y is expected to increase by...
