A research center claims that 24% of adults in a certain country would travel into space on a commercial flight if they could afford it. In a random sample of 1200 adults in that country, 27% 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. %. i ne percentage aauits in the country wno wouia travei into space on a commerciai Tiignt ir they couia arora it is not O D.
