Statistics and Probability with Applications for Engineers and Scientists Using MINITAB, R and JMP: краткое содержание, описание и аннотация

Предлагаем к чтению аннотацию, описание, краткое содержание или предисловие (зависит от того, что написал сам автор книги «Statistics and Probability with Applications for Engineers and Scientists Using MINITAB, R and JMP»). Если вы не нашли необходимую информацию о книге — напишите в комментариях, мы постараемся отыскать её.

Introduces basic concepts in probability and statistics to data science students, as well as engineers and scientists Aimed at undergraduate/graduate-level engineering and natural science students, this timely, fully updated edition of a popular book on statistics and probability shows how real-world problems can be solved using statistical concepts. It removes Excel exhibits and replaces them with R software throughout, and updates both MINITAB and JMP software instructions and content. A new chapter discussing data mining—including big data, classification, machine learning, and visualization—is featured. Another new chapter covers cluster analysis methodologies in hierarchical, nonhierarchical, and model based clustering. The book also offers a chapter on Response Surfaces that previously appeared on the book’s companion website.
Statistics and Probability with Applications for Engineers and Scientists using MINITAB, R and JMP, Second Edition Features two new chapters—one on Data Mining and another on Cluster Analysis Now contains R exhibits including code, graphical display, and some results MINITAB and JMP have been updated to their latest versions Emphasizes the p-value approach and includes related practical interpretations Offers a more applied statistical focus, and features modified examples to better exhibit statistical concepts Supplemented with an Instructor's-only solutions manual on a book’s companion website 
is an excellent text for graduate level data science students, and engineers and scientists. It is also an ideal introduction to applied statistics and probability for undergraduate students in engineering and the natural sciences.

23 A bag contains a nickel, quarter, and “dime”, with the dime being a fake coin and having two heads. A coin is chosen at random from the bag and tossed four times in succession. If the result is four heads, what is the probability that the fake dime has been used?

24 In a playground, there are 18 players, 11 of them boys and seven are girls. Eight of the boys and three of the girls are soccer players; the rest are basketball players. The name of each player is written on a separate slip, and then these slips are put into an urn. One slip is drawn randomly from the urn; the player whose name appears on this slip is given a prize. What is the probability that a soccer player gets the prize given that a boy gets the prize?

25 Let , and be mutually exclusive and exhaustive events in a sample space S, and let , and . Let B be another event in S such that . Find the probabilities and .

26 An industry uses three methods , and to train their workers. Of all the workers trained, 50% are trained by method , 28% by method , and the rest, 22%, by method . Further 10% of those trained by method do not perform their job well, while 5% trained by method and 15% by methods also do not perform their job well. A randomly selected worker does not perform his job well. Find the probability that the worker was trained by (a) method , (b) method , and (c) method .

27 Suppose that an insurance company finds that during the past three years, 60% of their policy holders have no accident, 25% had one accident, and the remaining 15% had two or more accidents. Further, from their past 10 year history, the insurance company concludes that those who did not have any accident have a 1% chance of having an accident in the future, while those who had one accident have a 3% chance of having an accident in the future. Those who had two or more accidents in the past three years have 10% chances having an accident in the future. Suppose that shortly after the above study, one of their policy holders has an accident. What is the probability that this policy holder did not have any accident in the past three years?

28 Suppose that in a bolt manufacturing plant, machines A, B, and C manufacture, respectively, 45%, 25%, and 30% of the bolts. It is observed that the three machines produce, respectively, 5%, 2%, and 3% defective bolts. If the bolts produced by these machines are mixed in a well‐mixed lot and then a randomly selected bolt is found to be defective, find the probability that the defective bolt is produced by (a) machine A, (b) machine B, and (c) machine C.

29 A poll was conducted among 1000 registered voters in a metropolitan area asking their position on bringing a casino in that city.
