Suppose, you have a set of 10 reaction time scores that range from 20-30 seconds with a mean of 25 and a standard deviation of 2. Now suppose, you realize you forgot to add one score to the distribution and you actually have 11 reaction time scores. The score that you forgot was 5. What effect will the addition of the score of 5 have on the mean?
