The average and standard deviation for SAT scores is 1108 and 198, respectively. The average and standard deviation for ACT scores is 22 and 6.2, respectively. Based on this information, answer the following questions: a. Assuming nothing about the distribution of SAT scores, at least what percentage of scores will be between 712 and 1504? b. Assuming that the distribution of SAT scores are normal, approximately what percentage of scores will be over 1504? c. If Jordan got 1200 on the SATs and a 30 on the ACTs, which exam did Jordan do better on? Justify your answer and show all work.
