A 10-year study conducted by the American Heart Association provided data on how age, blood pressure, and smoking relate to the risk of strokes. Data from a portion of this study are contained in the Excel Online file below. Risk is interpreted as the probability (times 100) that a person will have a stroke over the next 10-year period. For the smoker variable, 1 indicates a smoker and 0 indicates a nonsmoker. Construct a spreadsheet to answer the following questions.
A drug test correctly gives a positive result 90 percent of the time. However, 3 percent of the time, it incorrectly gives a positive result. This is known as a false positive. Suppose that 7 percent of the people to be tested will have one or more of the drugs being tested for in their system. What is the probability that a randomly chosen person will have get a positive test result? Your answer should be to 4 decimal places.
Alicia believes that the probability for the stock market to go down is 0.7 given that the economy deteriorates during pandemic covid-19. She also believes that the probability that the economy will deteriorate is 0.5. Based on the information above, what is the probability that the economy will deteriorate and the stock market will go down？
The chance that doctor A will diagnose a disease a disease X correctly is 60%. The chances that a patient will die by his treatment after correct diagnosis is 40% and the chance of death by wrong diagnosis is 70%. A patient of doctor A, who had disease X, died. What is the chance that his disease was diagnosed correctly ?
A drug test correctly gives a positive result 88 percent of the time. However, 3 percent of the time, it incorrectly gives a positive result. This is known as a false positive. Suppose that 5 percent of the people to be tested will have one or more of the drugs being tested for in their system. What is the probability that a randomly chosen person will have get a positive test result? Your answer should be to 4 decimal places.
Future scientists: Education professionals refer to science, technology, engineering, and mathematics as the STEM disciplines. A research group reported that 27% of freshmen entering college in a recent year planned to major in a STEM discipline. A random sample of &5 freshmen is selected. Round the answer to at least four decimal places. Part: 0 / 6 Part 1 of 6 Is it appropriate to use the normal approximation to find the probability that less than 32% of the freshmen in the sample are planning to major in a STEM discipline? It is v appropriate to use the normal curve, since np = v 10 and n (1 – p) = 1 V 10. Part: 1 / 6 Part 2 of 6 Find the probability that less than 32% of the freshmen in the sample are planning to major in a STEM discipline. The probability that less than 32% of the freshmen in the sample are planning to major in a STEM discipline is|1. Part 3 of 6 A new sample of 130 freshmen is selected. Find the probability that less than 29% of the freshmen in this new sample…
Semiconductor lasers used in optical storage products require higher power levels for write operations than for read operations. High-power-level operations lower the useful life of the laser. Lasers in products used for backup of higher-speed magnetic disks primarily write, and the probability that the useful life exceeds five years is 0.3611. Lasers that are in products that are used for main storage spend approximately an equal amount of time reading and writing, and the probability that the useful life does not exceed five years is 0.01. Now, 0.8185 of the products from a manufacturer are used for backup, while the remaining manufacturer's products are used for main storage. What is the probability that a laser that failed before five years came from a product used for backup? Select one: O a. 0.74426602 O b. 0.97305309 O c. 4.21231766 O d. 0.99654124
Professor Brown gives her students a maximum of three attempts to pass a final examination in her statistics course. She has found that the probability of passing on the first attempt is 0.40, the probability of passing the second attempt is 0.65 and the probability of not passing the third attempt is 0.15. Find the probability that a randomly selected student of hers will pass the final examination
A hacker breaking into a computer system has a 15% chance of breaking into a system in 2 minutes, a 25% chance after 5 minutes, and a 60% chance after 20 minutes. What is the expected time will take the hacker to get in?
A BSCE student is taking Calculus 2 and Engineering Data Analysis courses. The probability that he will pass Calculus 2 and Engineering Data Analysis is 2/3and 4/9, respectively. What is the probability that he will pass both courses if the probability of passing at least one course is 4/5.
A study tracked a large group of people for 10 years. At the start of the study, 20% were heavy smokers (H), 30% were light smokers (L), and 50% were non-smokers (N). The interest of the study was whether the people in the study died during the study (D) or not die (Dc ). The probability that a light smoker died during the study was twice that of the probability of a non-smoker dying. Also, the probability that light smoker died during the study was half that of the probability of a heavy smoker dying. A randomly selected person from the study died during the study. What is the probability that this person was a heavy smoker (given they died, what is the probability they were a heavy smoker H)?
