For the population of Jellystone bears, the mean weight is 400 pounds and the mean blood pressure is 150, and the SLR regression slope for predicting blood pressure using weight has been found to be 0.05. What is the SLR regression intercept for predicting blood pressure using weight?
Would I use the regression line to predict Y from X ? And what is the pattern of the scatterplot?
You spilled water on your calculations from (a) and can't remember what your estimated regression parameters are. But you do have two possible estimated errors for each of your initial four observations:
