Question
Test the claim that the proportion of men who own cats is larger than 25% at the .005 significance level.
The null and alternative hypothesis would be:
H0:μ=H0:μ=
H1:μ≠H1:μ≠
H1:μ≠H1:μ≠
H0:μ=H0:μ=
H1:μ<H1:μ<
H1:μ<H1:μ<
H0:p=0.25H0:p=0.25
H1:p<0.25H1:p<0.25
H1:p<0.25H1:p<0.25
H0:p=0.25H0:p=0.25
H1:p>0.25H1:p>0.25
H1:p>0.25H1:p>0.25
H0:p=0.25H0:p=0.25
H1:p≠0.25H1:p≠0.25
H1:p≠0.25H1:p≠0.25
H0:μ=H0:μ=
H1:μ>H1:μ>
H1:μ>H1:μ>
The test is:
two-tailed
left-tailed
right-tailed
In a random sample of 95 men, 22 men owned cats.
The P-value of this sample is (to 4 decimals).
Based on this we: Select an answer Reject the null hypothesis Fail to reject the null hypothesis
We address the original claim with the conclusion.
- There is insufficient evidence to reject the proportion of men who own cats is 25% with .005 significance level.
- There is insufficient evidence that the proportion of men who own cats is larger than 25% with .005 significance level.
- The proportion of men who own cats is larger than 25% with .005 significance level.
- The proportion of men who own cats is 25% with .005 significance level.
- The proportion of men who own cats is not 25% with .005 significance level.
