Confidence intervals and significance tests allow us to predict and test the ____________ slope of the relationship between the explanatory and response variables (x and y) You can also do this for y-intercept, but this is not something to worry about for the exam The AP exam will most likely ask you to use a ________________________ to make inference Remember, everything dealing with slope is in the row with the ______________________ (“constant” refers to the y-intercept) If you need to do them in the calculator… 1.
