A medical researcher says that less than 75% of adults in a certain country m required to be vaccinated. In a random sample of 200 adults in that country, 72% 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. D. The percentage of adults in the country who think that healthy children should be required to be vaccinated is not %. Let p be the population proportion of successes, where a success is an adult in the country who thinks that healthy children should be required to be vaccinated. State Ho and H₂. Select the correct choice below and fill in the answer boxes to complete your choice. (Round to two decimal places as needed.) OA. Ho p Ha: p= OD. Ho: P= Ha: p www. OB. Ho: P< Ha: p² OE. Ho: p2 Ha: p< OC. Ho: Ps Ha:p> OF. Ho:p> Ha: ps
