Question

Test the claim that the proportion of men who own cats is larger than 10% at the .10 significance level.

The null and alternative hypothesis would be:

H0:p=0.1H0:p=0.1
H1:p>0.1H1:p>0.1
H0:μ=0.1H0:μ=0.1
H1:μ<0.1H1:μ<0.1
H0:μ=0.1H0:μ=0.1
H1:μ>0.1H1:μ>0.1
H0:p=0.1H0:p=0.1
H1:p≠0.1H1:p≠0.1
H0:μ=0.1H0:μ=0.1
H1:μ≠0.1H1:μ≠0.1
H0:p=0.1H0:p=0.1
H1:p<0.1H1:p<0.1



The test is:

right-tailed
left-tailed
two-tailed



Based on a sample of 45 people, 15% owned cats

The test statistic is:  (to 2 decimals)

The critical value is:  (to 2 decimals)

Based on this we:

  • Reject the null hypothesis
  • Fail to reject the null hypothesis
