A medical researcher says that less than 86% 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, 82% think that healthy children should be required to be vaccinated. At a = 0.01, is there enough evidence to support the researcher's claim? Complete parts (a) through (d) below. 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.) A. More than % of adults in the country think that healthy children should be required to be vaccinated. B.
