You have created a new way of screening for the coronavirus. Your hope is that it is 99 % accurate. You run thetest 100 times but realize that 10 are compromised cannot be used. Given you still observe that your test isaccurate 87 times, can you calculate the probability of making such an observation if your test is indeed 99%accurate.a. 0.048513O b. 0.049003c. 0.294020O d. 0.016808e. 0.063760QueNotManFF

If you select a random sample of 15 items from a large batch in which there are 18% defective items, what is the chance you find more than one defective items in the sample? Round your answer to 4 decimal places. Suppose the probability of a person having the disease is 0.20, and a sample of 23 individuals is tested. What is the probability that no individual in this sample will have a disease? Round your answer to 4 decimal places. Suppose the probability of a person having the disease is 0.20, and a sample of 23 individuals is tested. What is the expected number of people with the disease in this sample. Do not round your answer.
Samuel F.B. Morse (1791 – 1872), the creator of Morse Code, claimed that 12% of all letters used in the English language were “e”s. Suppose random samples of 196 letters are selected from a book What is the probability that a random sample of 196 letters will contain at least 10% "e"s? Type your calculated z-score here. Express its value to the nearest hundredth (two decimal places). Type your probability here. Express its value to four decimal places. Do not round.
You are performing 4 independent Bernoulli trials with p = 0.1 and q = 0.9. Calculate the probability of the stated outcome. Check your answer using technology. (Round your answer to four decimal places.) two successes P(X = 2) =
Answer the following question Michael is given 5 wads of paper to shoot into the basket, with a 90% accuracy rate. What is the probability that Michael will be successful with at least 4 of those shots?
You may need to use the appropriate appendix table or technology to answer this question. The population proportion is 0.26. What is the probability that a sample proportion will be within ±0.04 of the population proportion for each of the following sample sizes? (Round your answers to 4 decimal places.) (a) n = 100 (b) n = 200 (c) n = 500 (d) n = 1,000 (e) What is the advantage of a larger sample size? There is a higher probability ?p will be within ±0.04 of the population standard deviation.We can guarantee p will be within ±0.04 of the population proportion p. As sample size increases, E(p) approaches p.There is a higher probability p will be within ±0.04 of the population proportion p.
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%
The failure time of a component is a random variable with an exponential distribution that has a mean of 41.9 years. What is the probability that the component will still be working after 135 years? Your answer: O 0.078 O 0.040 O 0.648 O 0.725 O 0.323 O 0.158 O 0.897 O 0.231 O 0.083 O 0.728
Sara is a 60-year-old Anglo female in reasonably good health. She wants to take out a $50,000 term (that is, straight death benefit) life insurance policy until she is 65. The policy will expire on her 65th birthday. The probability of death in a given year is provided by the Vital Statistics Section of the Statistical Abstract of the United States (116th Edition). x = age 60 61 62 63 64 P(death at this age) 0.00562 0.00842 0.00950 0.01065 0.01165 Using this probability and the $50,000 death benefit, what is the expected cost to Big Rock Insurance? (b) Repeat part (a) for ages 61, 62, 63, and 64. Age Expected Cost 61 $ 62 $ 63 $ 64 $ What would be the total expected cost to Big Rock Insurance over the years 60 through 64? If Big Rock Insurance wants to make a profit of $700 above the expected total cost paid out for Sara's death, how much should it charge for the policy? If Big Rock Insurance Company charges $5000 for the policy, how much profit does the…
