Amrit, I really appreciated your detail explanation, is it possible to represent how the detail explanation would be displayed in a graph in your response, Why does one develop a line of regression? What kind of outcomes from the line of regression make sense or does it have to be on the line to be valid? But what does it mean in the context of this problem to have a slope of 0.7 or a y-intercept of -0.1? Is this asking too much?Please forgive me, I am having a mental block tonight and trying to understand the concepts.
