A) Determine if the sample sizes are large enough
where :
ages between ( 18 to 29 )
p1 = 0.48 ,
n1 = 178 , ∴ n1 P1 = 85.44 also n1 ( 1 - p1 ) = 92.56
ages between ( 50 to 64 )
P2 = 0.03 ,
n2 = 427 ∴ n2p2 = 12.81 also n2( 1 -p2 ) = 414.19
<em>since all the values ae above 10 we can conclude that the sample sizes are large enough </em>
<em>answer = yes </em>
