Test the claim that the proportion of people who own cats is significantly different than 90% at the 0.1 significance level. The null and alternative hypothesis would be:

H0:p0.9H0:p0.9 H1:p<0.9H1:p<0.9 H0:=0.9H0:=0.9 H1:0.9H1:0.9 H0:0.9H0:0.9 H1:>0.9H1:>0.9 H0:p0.9H0:p0.9 H1:p>0.9H1:p>0.9 H0:0.9H0:0.9 H1:<0.9H1:<0.9 H0:p=0.9H0:p=0.9 H1:p0.9H1:p0.9 The test is:

right-tailed two-tailed left-tailed Based on a sample of 400 people, 97% owned cats The test statistic is: (to 2 decimals) The p-value is: (to 2 decimals) Based on this we:

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