Question

suppose you received a score of 95 out of 100 on exam 1. the mean was 79 and the standard deviation was 8. if your score on exam 2 is 90 out of 100, and the mean was 60 with a standard deviation of 15, then you did: group of answer choices

Answer 1

The z-score for both tests is the same that is 2.

Here we have to find the z-score.

To compare both scores, we need to compute the z-score of both exams and then compare the values.

The formula for z-score:

Z = (X - μ) σ

Here

X = score obtain

μ = mean score

σ = standard deviation

For exam 1:

Z = (95 - 79) / 8

= 16/8

= 2

For exam 2:

Z = (90 - 60)/ 15

= 30/15

= 2

Therefore z-score for both is 2.
