Chez Michelle, data were gathered for 10 customers. The data and summary statistics are shown in the table. The averages, along with standard deviations as well as the correlation coefficient are already calculated. If the total bill was the predictor variable and the tip is the response variable, then the residual for the estimated tip for a total bill of 126$ is Note: 1- Round your numbers to 3 decimal places and choose the answer that is closest to your answer.
