Answer

# Explanation: ## Step1: Define null hypothesis The null hypothesis ($H_0$) is a statement of no - effect or no - difference. Here, it assumes that the proportion of deaths among male adults due to heart diseases in Sonoma County is the same as the known proportion. $H_0: p = 0.20$ ## Step2: Define alternative hypothesis The alternative hypothesis ($H_a$) is what we are trying to find evidence for. Since we want to know if the percentage is different, it is a two - tailed test. $H_a: p\neq0.20$ # Answer: $H_0: p = 0.20$ $H_a: p\neq0.20$
