Hypothesis Testing Using a P-Value In Exercises 13–16, (a) identify the claim and state H0, and Ha, (b) use technology to find 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.
13. Space Travel A research center claims that 27% of U.S. adults would travel into space on a commercial flight if they could afford it. In a random sample of 1000 U.S. adults, 30% 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? (Source: Rasmussen Reports)
