The relationship between the cost of a taxi ride (y) and the length of ride (x) is analyzed and is determined to be linear. The mean length was 3.9 miles with a standard deviation of 0.8 mile(s). The mean cost was $9.49 with a standard deviation of $1.7. The equation of the regression model is: �'=2.53+ 1.79 x Explain in context what the number 1.79 in the regression model means. Explain in context what the number 2.53 in the regression model means. You take a cab ride for 6 miles. What is the predicted charge
