A study tracked a large group of people for 10 years. At the start of the study, 20% were heavysmokers (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(D°).The probability that a light smoker died during the study was twice that of the probability of anon-smoker dying. Also, the probability that light smoker died during the study was half that ofthe probability of a heavy smoker dying.A randomly selected person from the study died during the study. What is the probability that thisperson was a heavy smoker (given they died, what is the probability they were a heave smoker H)?

Given: P(H) = 0.20 P(L) = 0.30 P (N) = 0.50 P (D | L) = 2 P(D |N) P (D|L) = 0.5 P(D | H)

The life of light bulbs is distributed normally. The variance of the lifetime is 225and the mean lifetime of a bulb is 530 hours. Find the probability of a bulb lasting for at most 540 hours. Round your answer to four decimal places.
The probability of flu symptoms for a person not receiving any treatment is 0.024. In a clinical trial of a common drug used to lower cholesterol, 30 of 1156 people treated experienced flu symptoms. Assuming the drug has no effect on the likelihood of flu symptoms, estimate the probability that at least 30 people experience flu symptoms. What do these results suggest about flu symptoms as an adverse reaction to the drug? a. (a) P(Xgreater than or equals 30)equals (Round to four decimal places as needed.)
13% of all Americans suffer from sleep apnea. A researcher suspects that a higher percentage of those who live in the inner city have sleep apnea. Of the 386 people from the inner city surveyed, 62 of them suffered from sleep apnea. What can be concluded at the level of significance of a = 0.05? %3D
Based on information from a previous study, r1 = 30 people out of a random sample of n1 = 107 adult Americans who did not attend college believe in extraterrestrials. However, out of a random sample of n2 = 107 adult Americans who did attend college, r2 = 46 claim that they believe in extraterrestrials. Does this indicate that the proportion of people who attended college and who believe in extraterrestrials is higher than the proportion who did not attend college? Use ? = 0.01.
Based on information from a previous study, r1 = 38 people out of a random sample of n1 = 106 adult Americans who did not attend college believe in extraterrestrials. However, out of a random sample of n2 = 106 adult Americans who did attend college, r2 = 52 claim that they believe in extraterrestrials. Does this indicate that the proportion of people who attended college and who believe in extraterrestrials is higher than the proportion who did not attend college? Use α = 0.01.

Some commercial airplanes recirculate approximately 50% of the cabin air in order to increase fuel efficiency. The researchers studied 1102 airline passengers, among which some traveled on airplanes that recirculated air and others traveled on planes that did not recirculate air. Of the 519 passengers who flew on planes that did not recirculate air, 104 reported post-flight respiratory symptoms, while 113 of the 583 passengers on planes that did recirculate air reported such symptoms. Is there sufficient evidence to conclude that the proportion of passengers with post-flight respiratory symptoms differs for planes that do and do not recirculate air? Test the appropriate hypotheses using ? = 0.05. You may assume that it is reasonable to regard these two samples as being independently selected and as representative of the two populations of interest. (Use a statistical computer package to calculate the P-value. Use pdo not recirculate − pdo recirculate. Round your test statistic to two…
Running heart rate 50% of 18-25 year-olds will experience a heart rate of more than 120 beats per minute (bpm) after running a mile. Jose is a physician who is researching to what extent running affects heart rate in 18-25 year-olds. He believes that less than Jose recruits a random sample of 464 people between the ages of 18 and 25 to run a mile and records their heart rate. He finds that 184 have a heart rate of more than 120 bpm. Round all calculated answers to 4 decimal places. 1. Correctly state the null and alternative hypotheses. Но : р На : р くV 2.

Based on information from a previous study, r1 = 39 people out of a random sample of n1 = 105 adult Americans who did not attend college believe in extraterrestrials. However, out of a random sample of n2 = 105 adult Americans who did attend college, r2 = 50 claim that they believe in extraterrestrials. Does this indicate that the proportion of people who attended college and who believe in extraterrestrials is higher than the proportion who did not attend college? Use ? = 0.01.

The president of a local college reported that more than 25% of the students received a scholarships. To see if this is true, the registrar selected sample of 100 students and found that 22 received scholarships. At a=0.05, test the claim that more than 25% of the students have scholarships.
