Points: 0 of 1 could afford it. At $\alpha=0.05$, is there enough evidence to reject the research center's claim? Complete parts (a) through (d) below. (a) Identify the claim and state $\mathrm{H}_{0}$ and $\mathrm{H}_{\mathrm{a}}$. Identify the claim in this scenario. Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.) A. The percentage adults in the country who would travel into space on a commercial flight if they could afford it is not B. No more than $\square$ of adults in the country would travel into space on a commercial flight if they could afford it. C. $\square \%$ of adults in the country would travel into space on a commercial flight if they could afford it. D. At least $\square \%$ of adults in the country would travel into space on a commercial flight if they could afford it.

Step 1 ：Identify the claim in this scenario. The claim is usually the statement that we are trying to test. In this case, the claim is not explicitly stated in the question. However, it is implied that the research center has made a claim about the percentage of adults in the country who would travel into space on a commercial flight if they could afford it.

Step 2 ：State the null hypothesis (H0) and the alternative hypothesis (Ha). The null hypothesis is the statement that there is no effect or difference, and the alternative hypothesis is the statement that there is an effect or difference. H0: The percentage of adults in the country who would travel into space on a commercial flight if they could afford it is equal to p (the claim made by the research center). Ha: The percentage of adults in the country who would travel into space on a commercial flight if they could afford it is not equal to p (the claim made by the research center).

Step 3 ：We would need more information to fill in the exact values for p in the hypotheses.

Step 4 ：Final Answer: The claim is that a certain percentage of adults in the country would travel into space on a commercial flight if they could afford it. The null hypothesis (H0) is that the percentage of adults who would do so is equal to the claimed percentage, and the alternative hypothesis (Ha) is that the percentage of adults who would do so is not equal to the claimed percentage.
