Find the $P$-value obtained when testing the claim that $p=0.75$ when given sample data resulting in a test statistic of $z=1.20$.

Solution

VerifiedStep 1

1 of 2The test is two-tailed, then the P-value is the probability of finding a value equal to the z-score or more extreme:

$P(Z<-1.20\text{ or }Z>1.20)=2\times P(Z<-1.20)=2\times 0.1151=0.2302$
