Since r > 0, the correlation is positive. It's a weak correlation because r is closer to 0 than it is to 1.

A reasonable estimate is an educated guess made by an observer based on that person's current knowledge and following observations. For example, If Garth knew that he was 1.2 meters tall, and he observed that the door was approximately twice his own height, Garth could then make the reasonable estimate that the door is about 2.4 meters tall.
The answer is 313.56 because 289 + (8.5%=24.65)=313.56
