The mean for statistics test scores is 63 and the standard deviation is 6.0. For the biology test scores, the mean is 22 and the standard deviation is 4.1
A student gets a 74 on the statistics test and a 29 on the biology test.
A) Transform the statistics score to z score.
How far is 74 from 63?? 74-63 = 11
How many standard deviations is that?? 11/6
Therefore z = 11/6
============================
Transform the biology score to a z score.
z(29) = (29-22)/4.1 = 7/4.1 = 1.7073
=======
Cheers,
