A medical researcher says that less than 83% of adults in a certain country think that healthy children should be required to be vaccinated. In a random sample of 200 adults in that country, 80% think that healthy children should be required to be vaccinated. At α=0.05, is there enough evidence to support the researcher's claim? Complete parts (a) through (e) below. (a) Identify the claim and state H0 and Ha. Identify the claim in this scenario. Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.) B. Find the critical value(s) and identify the rejection region(s). Identify the critical value(s) for this test. z0= (Round to two decimal places as needed. Use a comma to separate answers as needed.) (c) Find the standardized test statistic z. z= (Round to two decimal places as needed.) (d) Decide whether to reject or fail to reject the null hypothesis and (e) interpret the decision in the context of the original claim. the null hypothesis. There enough evidence to the researcher's claim.

H0
and
Ha.
Identify the claim in this scenario. Select the correct choice below and fill in the answer box to complete your choice.
(Type an integer or a decimal. Do not round.)
