Roadblock State police set up a roadblock to estimate the percentage of cars with up-to-date registration, insur-ance, and safety inspection stickers. It would be too in-convenient and costly to check every vehicle that passes through a checkpoint, so they decide to stop about 1/20of the vehicles.a) Why would a simple random sample be unreasonablefor this situation.b) Identify two possible sampling schemes that could beused. Explain how randomization would be used in each.

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.
