STAT 10 Study guide for Test 2 1. Assume the random variable x is normally distributed...
Question 25 2 pts 9. There are two college entrance exams that are often taken by students, Exam 1 and Exam 2. The composite score on Exam 1 is approximately normally distributed with mean 21.5 and standard deviation 5. The composite score on Exam 2 is approximately normally distributed with mean 1029 and standard deviation 245. Suppose you scored 28 on Exam 1 and 1220 on Exam 2. Which exam did you score better on? Justify your reasoning using the...
