The equation of the least-squares regression line is hat y is equal to negative 146 point 7 plus 4 point 7 6 x , where hat y is the weight and x is the height. Which show the residual plot?
Answer
A
Image with description A dot plot with the x axis titled Height in Inches begins with 64 and ends at 78 with equal intervals of 4, such as 64, 66, 68, 70, 72, 76,and 78. The y axis titled Residual begins with negative 20 and ends at 20 with equal intervals of 5, such as negative 20, negative 15, negative 10, negative 5, 0, 5, 10, 15 and 20. A horizontal line parallel to the x axis starts from the point where y is 0. There is a dot at approximately 65, 2; a dot at 66, 7; a dot at 67, negative 3; a dot at 68, 8; a dot at 69, negative 18; a dot at 69, 7; a dot at 70, 2; a dot at 71, negative 14; a dot at 74, 10; and a dot at 76, 15.
