Question 773588
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
