Heights of American men aged 20 - 29 approximately follow a normal distribution with mean 70 inches and standard deviation 3 inches (reported in the Statistical Abstrac of the United States 1998). The same shape and spread hold for heights of women in this age group, but with mean 65 inches. Round your answers to parts a and b to four decimal places. a. Use this normal model to determine the probability that a randomly selected American man in this age group will be shorter than 64 inches tall. b. According to this normal model, what proportion of American men aged 20 - 29 feet or taller? are C. How tall must a man be to be among the tallest 10% of men in this age group? Round your answer to two decimal places. inches

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.
