A research center claims that 31% of adults in a certain oountry would travel into space on a commercial flight if they could afford it. In a random sample of 800 adults in that country, 33% say that they would travel into space on a commercial flight if they could afford it. At a = 0.01, is there enough evidence to reject the research center's claim? Complete parts (a) through (d) below O B. The peroentage adults in the country who would travel into space on a commercial flight if they could afford it is not %. O C. At least % of adults in the country would travel into space on a commercial fight if they could afford it. O D.
