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. No more than % of adults in the country would travel into space on a commercial flight if they could afford it. 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 Ho and H. Select the correct choice below and fill in the answer boxes to complete your choice. (Round to two decimal places as needed.) OA. Ho: p2 OB. Ho: P# OC. Họ: p< Ha:p= Ha: p2 Ha:p< O D. Ho: p> O E.

Types of Bias

Statistics is the study of data collection, organization, analysis, interpretation, and presentation. Statistical bias is a characteristic of a statistical technique or its findings in which the expected value deviates from the actual root quantitative parameter being estimated. According to the actual definition of bias, it refers to the tendency of a statistic to overestimate or underestimate a parameter.
