5. If the ratio of net income to sales for a restaurant is 5 percent, what is the predicted ratio of cash flow from operations to sales?
选项:
A.0.007 + 0.103(5.0) = 0.524.
B.0.077 -0.826(5.0) =-4.054.
C.0.077 + 0.826(5.0) = 4.207.
解释:
C is correct.
To make a prediction using the regression model, multiply the slope coefficient by the forecast of the independent variable and add the result to the intercept.
请问这题A哪里错呀?不是和C是一样的思路么
