A medical researcher says that less than 88% of adults in a certain country think that healthy children should be required to be vaccinated. In a random sample of 500 adults in that country, 85% 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 (e) below. When you know the number of successes x, the sample size n, and the population proportion p, it can be easier to use the formula shown below to find the standardized test statistic when using a z-test for a population proportion p. X- np z= Vnpg (a) Identify the claim and state H, and Ha Identify the claim in this scenario. Select the correct choice below and fill in the answer box to complete your choice.
