Question 345231
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?
----
Geography:
z(62) = (62-80)/15 = -1.2
------------------
Mathematics:
z(246) = (246- 300)/36 = -1.5
=====================================
The geography is the higher score relative to the other students.
