Explanation:

A manufacturer of computer memory chips produces chips in lots of 1000. If nothing has gone wrong in the manufacturing process, at most 7 chips each lot would be defective, but if something does go wrong, there could be far more defective chips. If something goes wrong with a given lot, they discard the entire lot. It would be prohibitively expensive to test every chip in every lot, so they want to make the decision of whether or not to discard a given lot on the basis of the number of defective chips in a simple random sample. They decide they can afford to test 100 chips from each lot. You are hired as their statistician.

There is a tradeoff between the cost of eroneously discarding a good lot, and the cost of warranty claims if a bad lot is sold. The next few problems refer to this scenario.

Problem 8. (Continues previous problem.) A type I error occurs if (Q12)

Problem 9. (Continues previous problem.) A type II error occurs if (Q13)

Problem 10. (Continues previous problem.) Under the null hypothesis, the number of defective chips in a simple random sample of size 100 has a (Q14) distribution, with parameters (Q15)

Problem 11. (Continues previous problem.) To have a chance of at most 2% of discarding a lot given that the lot is good, the test should reject if the number of defectives in the sample of size 100 is greater than or equal to (Q16)

Problem 12. (Continues previous problem.) In that case, the chance of rejecting the lot if it really has 50 defective chips is (Q17)

Problem 13. (Continues previous problem.) In the long run, the fraction of lots with 7 defectives that will get discarded erroneously by this test is (Q18)

Problem 14. (Continues previous problem.) The smallest number of defectives in the lot for which this test has at least a 98% chance of correctly detecting that the lot was bad is (Q19)

(Continues previous problem.) Suppose that whether or not a lot is good is random, that the long-run fraction of lots that are good is 95%, and that whether each lot is good is independent of whether any other lot or lots are good. Assume that the sample drawn from a lot is independent of whether the lot is good or bad. To simplify the problem even more, assume that good lots contain exactly 7 defective chips, and that bad lots contain exactly 50 defective chips.

Problem 15. (Continues previous problem.) The number of lots the manufacturer has to produce to get one good lot that is not rejected by the test has a (Q20) distribution, with parameters (Q21)

Problem 16. (Continues previous problem.) The expected number of lots the manufacturer must make to get one good lot that is not rejected by the test is (Q22)

Problem 17. (Continues previous problem.) With this test and this mix of good and bad lots, among the lots that pass the test, the long-run fraction of lots that are actually bad is (Q23)

A wire having a mass per unit length of 0.440 g/cm carries a 1.50-A current horizontally to the south. (a) What is the direction

coldgirl [10]

Answer:

B = 0.287 Tesla

According to thumb rule the direction of magnet is to the east.

Explanation:

F = BiL sin∅

note that F = mg

B = magnetic field

i = current

therefore,

mg = BiLsin∅

Make B subject of the formula

B = mg/iLsin∅

m/L = mass per length of the wire and it is given in gram per centimeter . It should be converted to kg per meter.

m/L = 0.440 g/cm

convert to kg/m = 0.440 × 0.001 kg × 100 m = 0.044 kg/m

B = 9.8 × 0.044 / sin 90 × 1.50 × 1

B = 0.4312/ 1.50

B = 0.28746666666

B = 0.287 Tesla

According to thumb rule the direction of magnet is to the east.

Identify the risks exist in the conversion cycle of Central Production Limited.

11111nata11111 [884]

Answer:

Authorization of transactions:- Because of unclear subjugation, there is a potential risk of entering a money transfer again and again. To minimize this, all workers should adopt the rules for specific purchases, such as maintaining a set pricing list and guarantee a limited error distance.

Explanation:

The following are the risks which currently exist in the Central Production Limited conversion cycle:-

Lack of a "Maker and Checker" concept:- It is important because it executes the role of a sort account executive to check that the instructions and demands presented are correct and are not replicated. It would be extremely effective that someone in a position of power and authority might supervise certain rates and with certain operations.

Use of Hard-copies:- The production center supervisor will temporarily suspend the use of such hard copies for each production process. It is not only a resource loss, but risks being lost or duplicated as well. It really would give them a better chance if all online requests could be collected which would be far more effective and could be seen by all stakeholders. It will also lead to better leadership and faster distribution of information.

Wastage:- Tests should be in place to determine why additional material is needed above the normal volume, and it should be approved by a senior authority to the superintendent of the production line.

Supply Chain Management:- Interactions between a variety of agencies are too many. Use an ERP (Enterprise Resource Planning) device to help in streamlining the entire process flow will serve them well.
