1. The problem statement, all variables and given/known data 265 students hire a tutor to help them improve their scores on the SAT test. The results are summarized in Math and Verbal score changes. Math: Mean change in score = 19, Standard Deviation of score changes = 65 Verbal: Mean change in score = 7, Standard Deviation of score changes = 49. a) Suppose one of the 265 students is selected at random, give an interval that is likely to contain the students change in the Math Score. I have to do the same for the Verbal as well. b) Suppose that randomly selected student increased their score on one of the tests by 140 points, which is more likely to be have that increase/why? 2. Relevant equations No mean is given, this is where I have become a little stumped. All the questions to date have included a mean (for example the mean score of the 265 students). This question gives me the mean change in score, then the std. deviation of those score changes. 3. The attempt at a solution I am having trouble making an attempt, not exactly sure where to start. Any help would be appreciated... thanks!
