Question 17 Problem 3. Part of an Excel output relating x (independent variable, which is the price of the product) and y (dependent variable, which is the sales of the product) is shown below. Some of the blanks are marked with "?". We also calculated the value E(x; - I) = 0.7, and I = 3.5. Please answer questions (Question 3.1. to 3.20) regarding problem 3.
