Question

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 1030 and standard deviation 245. Suppose you scored 22 on Exam 1 and 1290 on Exam 2. Which exam did you score better on? Justify your reasoning using the normal model. Choose the correct answer. Scores on the Exam 1 and Exam 2 equal Score on the Exam 1 was higher None of these Score on the Exam 2 was higher

00:02 Here given that in test a, a student score x1 is equal to 26 and the mean score, mu1 is equals to 20 .4.
00:19 Then given the standard deviation is for test b, given the student score, x2 is equal to the 1171 and mean is mu 2 is equals to the 1 ,024 and standard deviation new 2 is equals to the 198 so for test a in test a their score is equals to the x1 minus new 1 is divided by sigma 1 this is equals to the 26 minus minus minus 20 .4 divided by 5.
01:12 So this is equals to the 1 .12...
