Some electronic devices are better used than new: The failure rate is higher when they are new than when they are six months old. For example 53.20% of the personal music players of a particular brand have a flaw. If the player has the flaw, it dies in the first six months. If it does not have this flaw, then only 6.800% fail in the first six months. Yours died after you had it for three months. What are the chances that it has this flaw?

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.
