Question 286946
a student scores 62 on a geography test and 246 on a mathematics test. 
The geography test has a mean of 80 and a standard deviation of 15. 
The mathematics test has a mean of 300 and a standard deviation of 36. 
-------------------------------------------------------------
If the data for both tests are normally distributed, on which test did the student score better relative to the other students in each class?
-------------------------------------------------------------
Use the z-measure to answer the question.
---
Geography: z(62) = (62-80)/15 = -1.2
1.2 standard deviations below the mean
---
Mathematics: z(246) = (246-300)/36 = -1.5
1.5 standard deviations below the mean
----
The geography score is the better score.
