A high school math teacher claims that students in her class will score higher on math portion of the NAT than students in a colleague’s math class. The mean NAT Math score for 49 student in her class is 22.1 and the standard deviation is 4.8. On the other hand, the man NAT Math score for 44 of the Colleague’s students in 19.8 and the standard deviation is 5.4. At alpha = 0.10, is there enough evidence to support the claim of the teacher that her students will score better on math portion of the NAT than students in her colleague’s math class?
