On the first statistics test of the semester in an introductory statistics class, the test scores were approximately normally distributed with 4 = 83.2 and 0 =4.9. Let X= the test score of a randomly selected student. a. What percentage of students scored between an 80 and 90? Find P(80 < X <90). b. What percentage of students scored higher than a 90? c. On the most recent test the test scores were also approximately normally distributed with 4 - 86.9 and o = 2.1. On which test, the first test or this most recent test, was it more likely for a student to score higher than a 90? Explain
