You score a 105 on Exam 1 which has a mean of 30 and a standard deviation of 28. Then you score 675 on Exam 2 with a mean of 493 and a standard deviation of 150.
(Round numerical answers to one decimal place)
a) How many standard deviations are you away from the mean on Exam 1?
b) Which score is better? (Click to select)The score of 105The score of 675Both scores have the same relative positionUnable to determine with given information
Homework Answers
a)
z-score of Exam 1
= (105 - 30)/28
= 2.6786
b)
Exam 2
z-score = (675 - 493)/150
= 1.21333
Since z-score of Exam 1 > z-score of Exam 2
The score of 105 is better
