What is a residual? Explain when a residual is positive, negative, and zero. OA. A residual is the sum of the observed y-value of a data point and the predicted y-value on a regression line for the x-coordinate of the data point. A residual is positive when the point is below the line, negative when it is above the line, and zero when the observed y-value equals the predicted y-value. OB. A residual is the difference between the observed y-value of a data point and the predicted y-value on a regression line for the x-coordinate of the data point. A residual is positive when the point is above the line, negative when it is below the line, and zero when the observed y-value equals the predicted y-value. OC.

What is a residual? Explain when a residual is positive, negative, and zero.
OA. A residual is the sum of the observed y-value of a data point and the predicted y-value on a regression line
for the x-coordinate of the data point. A residual is positive when the point is below the line, negative when it
is above the line, and zero when the observed y-value equals the predicted y-value.
OB. A residual is the difference between the observed y-value of a data point and the predicted y-value on a
regression line for the x-coordinate of the data point. A residual is positive when the point is above the line,
negative when it is below the line, and zero when the observed y-value equals the predicted y-value.
OC. A residual is the difference between the observed y-value of a data point and the predicted y-value on a
regression line for the x-coordinate of the data point. A residual is positive when the point is below the line,
negative when it is above the line, and zero when the observed y-value equals the predicted y-value.
OD. A residual is the sum of the observed y-value of a data point and the predicted y-value on a regression line
for the x-coordinate of the data point. A residual is positive when the point is above the line, negative when it
is below the line, and zero when the observed y-value equals the predicted y-value.
