Test the claim that the proportion of people who own cats is significantly different than 90% at the 0.05 significance level.

The null and alternative hypothesis would be:

 

H0:p≥0.9
H1:p<0.9
 
H0:p=0.9
H1:p≠0.9
 
H0:μ≥0.9
H1:μ<0.9
 
H0:μ≤0.9
H1:μ>0.9
 
H0:μ=0.9
H1:μ≠0.9
 
H0:p≤0.9
H1:p>0.9



The test is:

 

A-left-tailed
B-right-tailed
C-two-tailed



Based on a sample of 400 people, 98% owned cats

The test statistic is:               (to 2 decimals)

The p-value is:                    (to 2 decimals)

Based on this we:

A-Reject the null hypothesis

B-Fail to reject the null hypothesis
