One student scored 54 on a math test for which the mean score was 50.5 and the standard deviation was 3.2. Another student scored 80 on a chemistry test for which the mean score was 75.2 and the standard deviation was 5.2. Which student (math or chemistry) had a "better" score relatived to the rest of the testtakers?

MathGuru,
Find both zscores.
Formula:
z = (x  mean)/sd
Once you have both zscores, compare the scores.
I hope this will help get you started.
