Given that,
possibile chances (x)=72
sample size(n)=200
success rate ( p )= x/n = 0.36
success probability,( po )=0.3
failure probability,( qo) = 0.7
null, Ho:p=0.3
alternate, H1: p>0.3
level of significance, α = 0.05
from standard normal table,right tailed z α/2 =1.645
since our test is right-tailed
reject Ho, if zo > 1.645
we use test statistic z proportion = p-po/sqrt(poqo/n)
zo=0.36-0.3/(sqrt(0.21)/200)
zo =1.852
| zo | =1.852
critical value
the value of |z α| at los 0.05% is 1.645
we got |zo| =1.852 & | z α | =1.645
make decision
hence value of | zo | > | z α| and here we reject Ho
p-value: right tail - Ha : ( p > 1.85164 ) = 0.03204
hence value of p0.05 > 0.03204,here we reject Ho
ANSWERS
---------------
null, Ho:p=0.3
alternate, H1: p>0.3
test statistic: 1.852
critical value: 1.645
decision: reject Ho
p-value: 0.03204
