Use the following information to answer the next four questions: Junior' s Clothing has collected sales and discount information from several "Big Saturday" sales events.   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)?
