A pharmaceutical manufacturer wants to determine the concentration of a key component of cough medicine that may be used without the drug's causing adverse side effect_s. A part ofthe analysis, a random sample of 45 patients is administered doses of varying concentration (X), and the severity of side effects (Y) is measured. The results include X = 87.9, Y = 155.6, SSx = 2152, SSXY = 4510.4, 55., = 12543. Find the regression line on on X. 0 y = 31.95 + D.36*x O y = 0.36 + 28.63 * x O y = 2.10 + 31.95 *x O y = 40.63 + 2.10 * x
