Expert Solution
Step 1

In order to test the claim that population proportion is greater than 0.3, that is, p>0.3, conduct a single proportion z-test. 

The hypothesis test contain two hypotheses: null hypothesis and alternate hypothesis. The alternate hypothesis is about the claim which is to be tested. 

If p-value<α, where, α is significance level, then null hypothesis can be rejected and it can be concluded that test is significant.
