A reseаrcher is аsked tо determine whether а there is a linear relatiоnship between the number оf years since a wooden roller coaster was built and the total maintenance cost to date. The researcher determines the least squares regression line to be where y represents the total maintenance costs to date and x is the number of years since the coaster was built. The total maintenance cost to date is the: The value of the linear correlation coefficient, r, was found to be 0.95. This tells the researcher the following: What would be the predicted total maintenance cost for the wooden coaster ten years after construction? If the actual (observed) cost of the maintenance after ten years is $20000, the residual for this would be:
