Question
Test the claim that the proportion of men who own cats is smaller than 20% at the .10 significance level.
The null and alternative hypothesis would be:
Based on a sample of 45 people, 13% owned cats
The test statistic is (to 3 decimals)
The critical value is (to 2 decimals)
Based on this we
The null and alternative hypothesis would be:
- H0:P=0.2
H1:P>0.2 - H0:U=0.2
H1:U>0.2 - H0:U=0.2
H1:U≠0.2 - H0:P=0.2
H1:P<0.2 - H0:P=0.2
H1:P≠0.2 - H0:U=0.2
H1:U<0.2
Based on a sample of 45 people, 13% owned cats
The test statistic is (to 3 decimals)
The critical value is (to 2 decimals)
Based on this we
- Fail to reject the null hypothesis
- Reject the null hypothesis
