Question

The proportion of people that own cats is 20%. A veterinarian believes that this proportion is smaller than 20% and surveys 500 people. Test the veterinarian's claim at the α=0.05α=0.05 significance level.

Preliminary:

Is it safe to assume that n≤0.05n≤0.05 of all subjects in the population?
- Yes
- No
Verify np(1−p)≥10.np(1-p)≥10. Round your answer to one decimal place.

np(1−p)=np(1-p)=

Test the claim:

The null and alternative hypotheses are
- H0:μ=0.2
  Ha:μ≠0.2
- H0:μ≥0.2
  Ha:μ<0.2
- H0:p=0.2
  Ha:p<0.2
- H0:μ≤0.2
  Ha:μ>0.2
- H0:p=0.2
  Ha:p≠0.2
- H0:p≤0.2
  Ha:p>0.2
The test is
