STATISTICS
We are sampling randomly from a distribution known to be bimodal. a) As our sample size increases, what's the expected shape of the sample's distribution? b) What's the expected value of our sample's mean? Does the size of the sample matter? c) How is the variability of sample means related to the standard deviation of the population? Does the size of the sample matter? d) How is the shape of the sampling distribution model affected by the sample size?
STATISTICS
Construct the Pareto chart. In a study of retractions in biomedical journals, 436 were due to error, 201 were due to plagiarism, 888 were due to fraud, 29 l were duplications of publications, and 287 had other causes (based on data from "Misconduct Accounts for the Majority of Retracted Scientific Publications," by Fang, Steen, Casadevall, Proceedings of the National Academy of Sciences of the United States of America, Vol. 110, No. 3). Among such retractions, does misconduct (fraud, duplication, plagiarism) appear to be a major factor?
