A store owner analyzes the relationship between the monthly advertising budget (in $1000s) and monthly sales (in $1,000,000s). Using the data from the past year, with the advertising budget as the independent variable, the store owner finds the line of best-fit is y'=0.07x+11.23 and the standard error of the estimate is 3.72. Interpret the standard error of the estimate. On average, the monthly sales differs by 3.72 from the line of best- fit y'=0.07x+11.23. The monthly advertising budget differs by $3.72 from the line of best- fit y'=0.07x+11.23. On average, the monthly sales differs by $3,720 from the line of best- fit y'=0.07x+11.23. On average, the monthly advertising budget differs by $3,720 from the line of best-fit y'=0.07x+11.23. The monthly sales differs by $3, 720 from the line of best-fit y'=0.07x+11.23
