Test the claim that the proportion of people who own cats is larger than 80% at the 0.01 significance level. The null and alternative hypothesis would be: �0:�=0.8 �1:�≠0.8 �0:�≤0.8 �1:�>0.8 �0:�≥0.8 �1:�<0.8 �0:�≥0.8 �1:�<0.8 �0:�≤0.8 �1:�>0.8 �0:�=0.8 �1:�≠0.8 The test is: left-tailed two-tailed right-tailed Based on a sample of 800 people, 89% owned cats The p-value is: (to 2 decimals) Based on this we: Reject the null hypothesis Fail to reject the null hypothesis
