  1. A directional research hypothesis

1: Directional Research hypothesis:- If number of teens who listen rap is greater the the number of teens who listen classical music or less then it will b directional hypothesis. Because one can predict direction(the effect of one variable is greater)


2: Non directional research hypothesis:- A non directional alternative hypothesis is appropriate because the researcher is interested in determining whether the the number of teen who listens to rap music are less or greater the number of teens who listen classical music.

3:The null hypothesis:-
The researcher is studying two groups. one group is teens who listen rap music and other group is teen who listens classical music.the null hypothesis always predicts that there will be no differences between the groups being studied
