• b)What is the model’s correlation coefficient? Comment on the strength of the relationship between the price and the number of dinners.
• c)Apply a 10% increase to the price point of $4.5 and calculate the predicted number of dinners sold at this new price. Compare this predicted sale with the current sale for the $4.5 price point and interpret the impact of this specific price increase on sales.
