A research center claims that 30​% of adults in a certain country would travel into space on a commercial flight if they could afford it. In a random sample of 800 adults in that​ country, 34​% say that they would travel into space on a commercial flight if they could afford it. At α=0.05​, is there enough evidence to reject the research​ center's claim? Complete parts​ (a) through​ (d) below. ​(a) Identify the claim and state H0 and Ha. Let p be the population proportion of​ successes, where success is an adult in the country who would travel into space on a commercial flight if they could afford it. State H0 and Ha. Select the correct choice below and fill in the answer boxes to complete your choice.   b) Use technology to find the​ P-value.   Identify the standardized test statistic.   Identify the​ P-value.   (c) Decide whether to reject or fail to reject the null hypothesis and​ (d) interpret the decision in the context of the original claim.
