This Test: 30 pts possible In a study of retractions in biomedical journals, 412 were due to error, 185 were due to plagiarism, 884 were due to fraud, 329 were due to duplications of publications, and 280 had other causes. Construct a Pareto chart. Among such retractions, does misconduct (raud, duplication, plagiarism) appear to be a major factor? Choose the correct Pareto chart below D. Retractions 600 Error Plagiarism Fraud Error Plagiarism Fraud Fraud Error Duplication Other Fraud ? Error Duplication Other Among such retractions, does misconduct (fraud, duplication, plagiarism) appear to be a major factor? O A. No, misconduct does not appear to be a major factor because the majority of retractions were due to misconduct. O B. No, misconduct does not appear to be a major tactor because the majority of retractions were not due to misconduct. Click to select your answer.Explanation / Answer
As per the information given,the correct Pareto chart is given by option (B)
Option (B) is correct.No,misconduct does not appear to be a major factor because the majority of retractions were not due to misconduct.
Given: Normally distributed with mean,u =98.24 and S.D, s = 0.51
Let X denote the body temperature of the adults in the group.
(a) Probability that X is within 3 standard deviations of the mean = P(-3 < Z < 3) = 0.9974
Thus, 99.74% is the answer
(b) P(97.21 < X < 99.25)
Thus, X is within 2 standard deviations of the mean =
P(-2 < Z < 2) = 0.9544
Thus, 95.44% is the answer
