A research center claims that 30% of adults in a certain country would travel into space on a commercial fight if they could afford it. In a random sample of 1200 adults in that country, 33% say that they would travel into space on a commercial flight if they could afford it. At a=0.05, is there enough evidence to reject the research center's claim?
