A. between 14-16 B. between 13-17 C. between 9-21 D. between 11-19 2 A student 94 on a history test and 315 on a foreign language test. the history test has a mean of 80 and standard deviation of 10. the foreign language test has a mean of 300 and standard deviation of 12. if the data for both test are normally distributed, on which test did the student score better relative to the other students in each class? A. the students scored better on the foreign language test B. the student scored better on the history test C. the student scored the same on both d. unable to determine
