Question 1135472: A medical school claims that more than 14% of its students plan to go into general practice. It is found that among a random sample of 99 of the school's students, 25% of them plan to go into general practice. Find the P-value for a test of the school's claim. Round to 4 decimals. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! Ho: p>0.14
Ha: p<=0.14
alpha = 0.05= p{reject Ho|Ho true}
test stat is a 1 sample proportion z=(phat-po)/sqrt((p*(1-p))/n)
phat is 0.25 use exact since dealing with people.
z=0.11/sqrt(0.25*0.75/99)=2.53
p-value=0.0057 (reject Ho)
