Suppose that in a production run of 40 units, 4 are defective. A sample of 4 units are to be randomly drawn from the 40. What is the probability that 2 or more are defective if the samples are drawn with replacement?
Suppose that out of a class of size 32, 2 students received a grade of "A". The frequency of students receiving an "A" would be...
4.a) Find the savings between the total cost of the current production run size and the optimal run size. b) Find the additional savings in production costs and ordering and holding costs with the proposed project. Calculate the payback period for the investment in the project. The anticipated annual demand for a chemical product distributed by the Seanna Chemical Group is 25,000 tons per year for the coming year. The company is currently producing the product with a capacity of...
Suppose a study is being planned to estimate the relative frequency of companies that are labeled as risky. What sample size is needed so that the standard error will be no larger than 0.016 ?
Suppose that you are the manager of a production department that uses 2400 boxes of rivets per year. The supplier quotes you a price of $9.50 per box for an order size of 199 boxes or less, a price of $9.00 per box for orders of 200 to 499 boxes, and a price of $8.00 per box for an order of 500 or more boxes. You assign a holding cost of h=20 percent of the price to this inventory. What...
Relative to your answer in Q2, how would the probability of accepting change if the sampling conditions are updated Old conditions: Sample size of 89, reject if more than 2 items found defective, lot is 3.5% defective New conditions: Sample size of 45, reject if more than 1 item is found defective, lot is 3.5% defective Group of answer choices Increased chance of accepting Decreased chance of accepting Same chance of accepting
Question 1 Question 1) (15) Suppose the table below represents the relative frequency of the number of defective items produced per day for a sample 25 days. Number of Defective Items (X) Number ofdays Pr(X-i) 距1 Pr(X =x) 4 a) Fill in the Probability distribution of X. Sketch a graph illustrating the p.d. (2.5) b) Fil in the cumulative distribution of X. Sketch a graph illustrating the c.d. (2.5) c) Calculate the expected value of X. Explain the meaning of...
Suppose that 4 tables in a production run of 50 are defective. A sample of 7 is to be selected to be checked for defects 9. How many different samples can be chosen? a. How many samples will contain at least one defective table? b. What is the probability that a randomly chosen sample of 7 contains at least one defective table? c. Suppose that 4 tables in a production run of 50 are defective. A sample of 7 is...
pose that 5% of the screws a company sells are defective. Figure B.7 shows sample proportions from two sampling dis- tributions: One shows samples of size 100, and the .15 Defective Screws Sup other shows samples of size 1000. (a) What is the center of both distributions? (b) What is the approximate minimum and maxi- mum of each distribution? (c) Give a rough estimate of the standard error in each case. (d) Suppose you take one more sample in each...
