You are now empowered to find an equation which will be able to predict for people how much weight they can expect to lose in a given time. Provided you are given some data, of course.
Here is the data:
This time you will not have to go through all the trouble of finding mean square errors because there is a handy program that will do it for you.
But, you still have to keep track of the slope and intercepts with their appropriate mean square error to find out the lowest one. Got it?
Go on to the program and find that equation!!!
