Test the claim that the proportion of people who own cats is larger than 90% at the 0.01 significance level. The null and alternative hypothesis would be: H0:p≥0.9H0:p≥0.9 H1:p<0.9H1:p<0.9 H0:p≤0.9H0:p≤0.9 H1:p>0.9H1:p>0.9 H0:μ≥0.9H0: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: right-tailed left-tailed two-tailed Based on a sample of 800 people, 92% owned cats The test statistic is: (to 2 decimals) The p-value is: (to 2 decimals) Based on this we: Reject the null hypothesis Fail to reject the null hypothesis
