This is shown in the table below: Sales ($) $3,250 $2,450 $2,850 $2,800 $2,500 $3,400 $3,250 $3,800 Discount 30% 15% 25% 20% 20% 30% 25% 35%
1. Plot the data. Does there seem to be a linear relationship between the discount offered and sales on "Big Saturday" events? Yes or No
2. Calculate a regression line for this data (use whole numbers for the percent discount, that is, use 15 for 15%). What is the value of the slope coefficient?
3. What is the value of the intercept coefficient for your regression line?
4. If Junior offers a 15% discount at the next "Big Saturday" event, what is your forecast of sales (based on your regression line)?
