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:
$H_0: p = 0.20$
$H_a: p\neq0.20$
