Fitting a straight line to a set of data yields the following prediction line.Complete (a) through (c) below.\ 1=18-07X \ \ a. Interpret the meaning of the Y-intercept. bo.Choose the correct answer below.\ OA.The Y-intercept,b= 18, implies that when the value of X is 0, the mean value of Y is 18.\ O B.The Y-intercept,bo=18, implies that for each increase of 1 unit in X,the value of Y is expected to increase by 18 units. OC.The Y-intercept, bo=18, implies that the average value of Y is 18\ OD.The Y-intercept, bp = - 0.7, implies that when the value of X is 0,the mean value of Y is -0.7.\ b. Interpret the meaning of the slope, by.Choose the correct answer below.\ O A. The slope, by = 0.7, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 0.7 units. O B.The slope, by = - 0.7, implies that for each increase of 1 unit in X, the value of Y is estimated to decrease by 0.7 units. O C. The slope, b, = 18, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 18 units. O D.The slope, b1 = - 0.7, implies that the average value of Y is - 0.7. c. Predict the mean value of Y for X= 4. Y1=\\\\geoquad (Type an integer or a decimal )
