A cognitive psychologist chose a random sample of 13 individuals from his department’s participant pool and for each individual he obtained a measure of hypnotizability (x) and duration of a color aftereffect (y) from each individual. The mean and standard deviation of x were mx = 12 and sx = 4, respectively, and the estimated standard error of estimate was sest = 3.48. If the regression equation is 5.35 + 0.75(x), what is the estimated standard error of ŷ when x = 16?
0.68
1.39
0.35
1.25
