In an election, 66% of the voters were Republicans, and 34% were not. Of the Republicans, 60% voted for Candidate X, and of the non-Republicans, 10% voted for Candidate X. Consider a randomly selected voter. Define A = Voter is Republican B = Voted for Candidate X (a) Find the values. P(A) = P(AC) = P(B|A) = P(B|AC) = (b) Find P(A and B).   Write in words what outcome it represents. This is the probability of being a non-Republican and voting for a Republican.This is the probability of being a Republican and voting for Candidate X.     This is the probability of being a Republican and voting for a Republican.This is the probability of being a non-Republican and voting for Candidate X. (c) Find P(AC and B).   Write in words what outcome it represents. This is the probability of being a Republican and voting for Candidate X.This is the probability of being a Republican and voting for a Republican.     This is the probability of being a non-Republican and voting for Candidate X.This is the probability of being a non-Republican and voting for a Republican. (d) Using the results in parts (b) and (c), find P(B). (Hint: The events in parts (b) and (c) cover all of the ways in which B can happen.)   (e) Use the result in part (d) to state what percent of the vote Candidate X received.

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.
