A lightbulb manufacturer ships large consignments of lightbulbs to big industrial users. When the production process is functioningcorrectly, which is 90% of the time, 10% of all bulbs produced are defective. However, the process is susceptible to an occasionalmalfunction, leading to a defective rate of 30%. If a defective bulb is found, what is the probability that the process is functioningcorrectly? If a nondefective bulb is found, what is the probability that the process is operating correctly?...If a defective bulb is found, the probability that the process is functioning correctly is(Round to three decimal places as needed.)

The principle of redundancy is used when system reliability is improved through redundant or backup components. Assume that a student's alarm clock has a 19.1% daily failure rate. Complete parts (a) through (d) below. a. What is the probability that the student's alarm clock will not work on the morning of an important final exam? -(Round to three decimal places as needed.) b. If the student has two such alarm clocks, what is the probability that they both fail on the morning of an important final exam? -(Round to five decimal places as needed.) c. What is the probability of not being awakened if the student uses three independent alarm clocks? -(Round to five decimal places as needed.) d. Do the second and third alarm clocks result in greatly improved reliability? A.Yes, because you can always be certain that at least one alarm clock will work. B.No, because the malfunction of both is equally or more likely than the malfunction of one. C.Yes, because…
A new surgery is successfully 85% of the time . If the results of 7 such surgeries are randomly sampled, what is the probability that at least 5 of them are successful. Carry your intermediate computations to at least four decimal places, and round your answer to two decimal places.
When functioning correctly, a machine produces switches with a 0.8% defective rate. Find the probability that a batch of 1,000 switches contains 14 or more defective switches (assuming that the machine functions correctly, i.e., the population defective rate is 0.8%). Suppose a batch of 1,000 switches were inspected when completed, and 14 defective switches were found. Based on your answer to part a, does this sample imply that the machine needs adjustment? Explain your answer.
A lightbulb manufacturer ships large consignments of lightbulbs to big industrial users. When the production process is functioning comectly, which is 90% of the time, 15% of all bulbs produced are defective. However, the process is susceptible to an occasional malfunction, leading to a defective rate of 30%. If a defective bub is found, what is the probability that the process is functioning correctly? If a nondefective bulb is found, what is the probability that the process is operating comectly? If a defective bulb is found, the probability that the process is functioning correctly is (Round to three decimal places as needed) CUP
An experiment consists of rolling a weighted die. The probability of rolling each number is: Pr[1]=0.05Pr[1]=0.05, Pr[2]=0.25Pr[2]=0.25, Pr[3]=0.1Pr[3]=0.1, Pr[4]=0.15Pr[4]=0.15, Pr[5]=0.2Pr[5]=0.2, and Pr[6]=0.25Pr[6]=0.25. On the first roll, you record if the number is Small (1,2) or Large (3,4,5,6). If the first number is Small, then on the second roll you record if the number is a 1 or not. If the first number is Large, on the second roll you record whether the number is Small or not. So, some typical outcomes would be S1 (small number rolled, then 1) or LL (large number rolled, then another large number). Draw a tree diagram and use it to answer the following questions. (1) What is Pr[S1]? (2) What is Pr[LL]? (3) What is Pr[(not1)onsecondroll|Sonfirstroll]? (4) What is Pr[S on second roll|L on first roll]?
The Watts New Lightbulb Corporation ships large consignments of lightbulbs to big industrial users. When the production process is functioning correctly, which is 90% of the time, 10% of all bulbs produced are defective. However, the process is susceptible to an occasional malfunction, leading to a defective rate of 50%. If a defective bulb is found, what is the probability that the process is functioning correctly? If a nondefective bulb is found, what is the probability that the process is operating correctly?
Suppose that we have test for lung cancer, which correctly identifies those with the cancer 70 % of the time, and mistakenly identifies those without the cancer 5 % of the time. In the cohort of interest, the rate of this cancer is somewhat low: 0.9 %. Find the probability -- a number between 0 and 1 -- that someone diagnosed (testing positive) with this test actually has lung cancer.
A blockchain-based business received consensus validation via two different systems A and B. The time between validations for each validation system in a typical day is known to be exponentially distributed with a mean of 3.2 seconds. Both systems operate independently. Given the above distribution, the probability that no validation will be received from system A in a 5-second period is (expressed your answer in 4 decimal places). Likewise, the probability that no validation will be received from both systems in a 5-second period is (expressed your answer in 4 decimal places). If X denotes the number of validations in a 5-second interval. Then, X is a Poisson random variable with the lambda is equal to (expressed your answer in 4 decimal places). Then, the probability that both systems receive two validations between 10 and 15 seconds after the site is (expressed in 4 decimal places). officially open for business is
A report to Health Canada indicated that an intensive education program was used in an attempt to lower the rate of lung cancer development among females. After running the program, a long-term follow-up study of 40a females was conducted, which revealed the current rate of lung cancer development is 7.a %. (a=1) Find the probability that 10 or less females have lung cancer development.
Question 6 Company records show that the proportion of defective parts has historically been 5%, however a quality control engineer believes that due to budget cuts these numbers have increased. To test this claim a random sample of N = 15 parts will be taken and if more than two defective parts are found the inspector will conclude that the proportion of defective parts has increases. Calculate the probability of the type one error. 18.5% 81.5% О 3.6% O 96.4%
