Question 1179412
Ho:p <=0.49
Ha: p > 0.49
alpha=0.01 p{reject Ho|Ho true}
test stat is a z from a 1 way 1 proportion test
critical value is z> 2.326
z=(p hat-p)/sqrt (p*(1-p)/n)
=0.04/sqrt(0.49*0.51/1000); sqrt term=sqrt(0.0002499)=0.0158
z=2.531
reject Ho, the true proportion is greater than 49%
p-value=0.0057
