This is a useful skill but, ofeourse. lacks the precision of estimating 1" using the regression equation. Estimate the value of Yvisually to the nearest 0.2 units if you can. Your answer: Bh Learn Question 2: Using the regression equation. estimate the value of 1' when the serotonin level is 0.50. Your
