If number of teens who listen rap is greater than the nubmer of teens who listen classical music OR less that it will be directional hypothesis .
Because we predict directional hypothesis when one variable effects is greater than other variable.
(2) Non-directional research Hypothesis :
The researcher is interested in determining whether the number of teens who listens to rap music are less or greater the number of teens who listen classical music.
