Suppose our favorite river (river A) to paddle has a gauge on it but there is no phone number to obtain a reading. However, river B has a gauge whose reading is available on the web. The last four times we paddled river A, we wrote down the levels for A and B.
A 3.0 4.0 3.5 3.2
B 2.0 2.5 2.3 2.2
a. Use linear regression to find the prediction equation. What would we predict A to be if B is at 2.1?
b. Is there evidence that there is a relationship between the water level on A and the water level on B?
Use a hypothesis test showing all steps.
