Question
Test the claim that the proportion of people who own cats is significantly different than 40% at the 0.05 significance level.

The null and alternative hypothesis would be:

 

H0:μ≤0.4H0:μ≤0.4
H1:μ>0.4H1:μ>0.4
H0:μ≥0.4H0:μ≥0.4
H1:μ<0.4H1:μ<0.4
H0:μ=0.4H0:μ=0.4
H1:μ≠0.4H1:μ≠0.4
H0:p≥0.4H0:p≥0.4
H1:p<0.4H1:p<0.4
H0:p=0.4H0:p=0.4
H1:p≠0.4H1:p≠0.4
H0:p≤0.4H0:p≤0.4
H1:p>0.4H1:p>0.4


The test is:

 

two-tailed
left-tailed
right-tailed


Based on a sample of 600 people, 32% owned cats

The p-value is:  (to 2 decimals)

Based on this we:
  • Reject the null hypothesis
  • Fail to reject the null hypothesis
