For one tests distribution mu 430 sigma 92 and another tes

For one tests distribution (mu = 430, sigma = 92) and another tests distribution (mu = 23, sigma = 6) which score is relatively higher, a score of 630 on the first test or a score of 30 on the second test? Explain. Select the most appropriate answer from those below.

Solution

Z score of 1st =(630-430)/92 = 2.17

Z score of 1st =(30-23)/6 =1.16

so the answer is.

A) the 1st score is relatively higher than the 2nd score because the Z score of the 1st is greater tha z score of 2nd
