In a typical package of jellybeans, 40% of the candies are orange. Five, 5, jellybeans are selected from small jellybean package that contains 20 candies. If X represents the number of orange jellybeans, then determine each of the following. Show all work, use proper notation and provide a therefore statement. Round to the nearest thousandth (3 decimal places) for each probability. a) P(X = 3) if each jellybean is put back in the package after it is selected. b) P(X = 3) if each jellybean is not put back in the bag after it is selected. c) E(X) if each jellybean is put back in the bag after it is selected.

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.
