A: Introduction: Denote p as the true proportion of people who own cats.
Test the claim that the proportion of men who own cats is significantly different than 20% at the 0.02 significance level.
The null and alternative hypothesis would be:
H1:p>0.2
H1:μ>0.2
H1:μ<0.2
H1:p<0.2
H1:μ≠0.2
H1:p≠0.2
The test is:
Based on a sample of 200 people, 22% owned cats
The test statistic is: (to 2 decimals)
The positive critical value is: (to 2 decimals)
Based on this we:
- Fail to reject the null hypothesis
- Reject the null hypothesis
