Is a linear model appropriate for these data? Yes O No (b) Calculate the slope and y-intercept for the regression line. (Round your answers to four decimal places.) Attendance = * (Inches of Snow) + X (c) Use your rounded equation to predict attendance at a concert when there are 1.3 inches of snow on the ground. (Round your answer to the nearest integer.) people
