there is no difference between the proportions of Indian and Asian young people who listen to rap music every day.
Step-by-step explanation:
Given a sample survey compared 634 randomly chosen Indians aged 15 to 25 with 567 randomly selected Asians in the same age group.

Null hypothesis H0: there is no difference between the proportions of Indian and Asian young people who listen to rap every day.

Alternative hypothesis:- 
Level of significance α = 0.05
The test of statistic

where 
p = 0.414
and q = 1-p = 1- 0.414 =0.586

on calculation , we get
z = 0.300 ><1.96 at 95 % level of significance
