Answer

# Explanation: ## Step1: Identify the claim The humane - society claims that less than 67% (or \(p < 0.67\)) of households own a pet. The null hypothesis \(H_0\) is the statement of no effect or no difference, and the alternative hypothesis \(H_a\) is the claim we are trying to find evidence for. ## Step2: Formulate the hypotheses The null hypothesis \(H_0\) is the opposite of the claim for testing purposes. So, \(H_0:p\geq0.67\) and \(H_a:p < 0.67\). # Answer: The claim is "Less than 67% of households in the country own a pet". The null hypothesis \(H_0:p\geq0.67\) and the alternative hypothesis \(H_a:p < 0.67\)
