Sandy asks…10 points! Calculate the margin of error (told mean, sd and n)?A sample of 24 students measured their reaction time by recording the distance a dropped ruler fell before they caught it. This was then repeated to see whether a learning effect was present. The mean decrease in drop distance between the two trials was 2.73 cm with standard deviation 2.601 cm. The margin of error for a 95% confidence interval for the mean decrease in drop distance for all students is?
