One division of a large defense contractor manufactures telecommunication equipment for the military. This division reports that 12% of non-electrical components are reworked. Management wants to determine if this percentage is the same as the percentage rework for the company's electrical components. The Quality Control Department plans to check a random sample of the over 10,000 electrical components manufactured across all divisions. The resulting 95% confidence interval based on these data is .0758 to .1339. Which of the following is the correct interpretation?a. The percentage of electronic components that are reworked is between 7.6% and 13.4%.
b. None of these.
c. We are 95% confident that between 7.6% and 13.4% of electrical components are reworked.
d. The margin of error for the true percentage of electrical components that are reworked is between 7.6% and 13.4%.
e. All samples of size 450 will yield a percentage of reworked electrical components that falls within 7.6% and 13.4%.

Me on this one i will give you 20pts. answer should be in detail . this is the discussion topic. one of the most fiercely debated topics in sports is the hot hand theory. the hot hand theory says that success breeds success. in other words, rather than each shot a basketball player takes or each at-bat a baseball player has being an independent event, the outcome of one event affects the next event. that is, a player can get hot and make a lot of shots in a row or get a lot of hits in a row. the hot hand theory, however, has been shown to be false in numerous academic studies. read this article, which discusses the hot hand theory as it relates to a professional basketball player. state whether you agree or disagree with the hot hand theory, and give reasons for your opinion. be sure to use some of the terms you’ve learned in this unit, such as independent event, dependent event, and conditional probability, in your answer.
