A researcher wants to test whether the average exam scores of two students groups (X and Y respectively) are same or not. How will he formulate null hypothesis (H0) and alternative hypothesis (H1)?
|
H0: X<Y, H1: X>Y |
|
H0: Y<X, H1: Y>X |
|
H0: X=Y, H1: X<Y |
|
H0: X=Y, H1: X>Y |
|
H0: X=Y, H1: X≠Y |
Yanıt Açıklaması:
The null hypothesis is that the average grades are same (X=Y) and the alternative is that they are not same (X≠Y). So the answer is choice E.
