e-commerce retailer was trying to understand how customer engagement correlates to customer purchases. They built the following regression model: Probability of Purchase = 0.1619 + 0.07 Emails Opened.  If someone opens 5 emails how likely are they to purchase?  If someone has a 75% chance of purchase how many emails have they opened?  If someone opens no emails how likely are they to purchase? What is the slope here and what does it tell us?
