A.


Upper H 0 : p equals 0.15H0: p=0.15

Upper H 1 : p not equals 0.15H1: p≠0.15






B.


Upper H 0 : p equals 0.15H0: p=0.15

Upper H 1 : p less than 0.15H1: p<>






C.


Upper H 0 : p greater than 0.15H0: p>0.15

Upper H 1 : p equals 0.15H1: p=0.15






D.


Upper H 0 : p equals 0.15H0: p=0.15

Upper H 1 : p greater than 0.15H1: p>0.15


Your answer is correct.




E.


Upper H 0 : p less than 0.15H0: p<>

Upper H 1 : p equals 0.15H1: p=0.15
