A supermarket buys oranges from a certain company, that claims that the fraction of un-acceptable fruit (e.g., rotten) in each shipment does not exceed 3%. The supermarket is willing to accept such (but not higher) percentage of bad fruit. The procedure agreed upon specifies that a random sample of 30 oranges will be selected from each shipment (the method of sampling is typically also a part of the protocol). The shipment will be accepted if there is no more than one unacceptable fruit in this sample, and rejected (or bought at a discounted price, etc.) otherwise. Compute and interpret the size of the test and the power function.

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.
