1)

The linear regression equation above is for Data Set 2. What is the predicted value for 'y' when the independent variable (x) is 43?

You are given the equation for the line, which gives you the value for 'a' and 'b', which can then be used in the App bivarequ2predict. If you have an existing value, it will also find out the residual for you - but in these questions, there are no existing values given (unless you look up data set 2), and therefore you would just use zero for the 'raw value' question on the App.

If you have an existing value, it will also find out the residual for you - but in these questions, there are no existing values given (unless you look up data set 2), and therefore you would just use zero for the 'raw value' question on the App.
