approximately bell-shaped. Compare the z-scores for the actors in the following situation. Best Supporting Actor winners at an awards ceremony. The distributions of the age Best Actor Best Supporting Actor H = 49.0 H= 44.0 O = 9.5 O = 14 In a particular year, the Best Actor was 53 years old and the Best Supporting Actor was 44 years old. Determine the z-scores for each. Best Actor: z = 23.0 Best Supporting Actor: z = 24.5 (Round to two decimal places as needed.)

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.
