A research center claims that 26% 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, 30% say that they would travel into space on a commercial flight if they could afford it. At a = 0.10, is there enough evidence to reject the research center's claim? Complete parts (a) through (d) below. Let p be the population proportion of successes, where a success is an adult in the country who would travel into space on a commercial flight if they could afford it. State H, and H. Select the correct choice below and fill in the answer boxes to complete your choice. (Round to two decimal places as needed.) Ho: p= 0.26 O B. Ho: P> OC. Họ: p# Ha p+ 0.26 Ha: ps Ha:p= O D. Ho: P< O E. Ho: p2 OF. Ho: ps Ha: p2 Ha: p< H:p> (b) Use technology to find the P-value. Identify the standardized test statistic. z=2.46 (Round to bwo decimal places as needed )
