Question 18 (1 point) Consider the following linear model: y = a+ 2.2x This linear model forecasts total book sales in units (in 1,000s) given the total amount of pre-order sales (in $1,000) identified by variable x. Calculate the value of the intercept (y-intercept) given that if the amount of pre-order sales is $1000 then the predicted sales volume is y = 24200 units. (Hint: notice that both X and y are expressed in 1000 units in the regression model). Note: 1- Only round your final answer to 1 decimal place. Enter your final answer with 1 decimal place. Your
