stKAccording to a study done by Nick Wilson of Otago University Wellington, the probability a randomly selected individual will not cover his or her mouth when sneezingis 0.267. Suppose you sit on a bench in a mall and observe people's habits as they sneeze. Complete parts (a) through (c).(a) What is the probability that among 12 randomly observed individuals, exactly 5 do not cover their mouth when sneezing?Using the binomial distribution, the probability is(Round to four decimal places as needed.)

In a recent study about the effects of obesity on blood pressure, 219 at risk patients were sampled, 90 of whom were obese, 73 of whom had high blood pressure (i.e., hypertension), and 61 of whom were obese with hypertension. a. What is the probability that a randomly-selected patient is obese or is diagnosed with hypertension? P (Obese or Hypertension): Round to 3 significant digits b. What is the probability that a randomly-selected patient is not at an increased risk (i.e. not have both effects simultaneously)? P(Not at an increased risk): Round to 3 significant digits L SUBMIT QUESTION SAVE PROGRESS SUBN
According to a survey, 30% of college students said that they spend too much time on Facebook. Suppose this result holds true for the current population of all college students. A random sample of six college students is selected. a. Define the random variable X b. X takes on what values?X = ..................................................... c. Determine the number of trials n and the probability of success for this binomial distribution. d.Find the probability that exactly three of these six college students will say that they will spend too much time on Facebook. Round your answer to three decimal places.
Dr. Verde conducted an experiment in which she randomly assigned each subject a colored pencil and then asked them to choose their favorite color. Her results showed that neither the distribution of the assigned pencil colors or the subjects' preferred colors conformed to their expected theoretical probability values. If she repeats the experiment with a much larger sample, how would you expect her results to change and why? Answer in complete sentences. UPLOAD
Based on a poll, 70% of Internet users are more careful about personal information when using a public Wi-Fi hotspot. What is the probability that among threethree randomly selected Internet users, at least one is more careful about personal information when using a public Wi-Fi hotspot? How is the result affected by the additional information that the survey subjects volunteered to respond? The probability that at least one of them is careful about personal information is? (Round to three decimal places as needed.) How is the result affected by the additional information that the survey subjects volunteered to respond? A. It is very possible that the result is not valid because not everyone uses public Wi-Fi. B. The result should not be impacted by this because volunteers are likely to have the most relevant responses. C. The result should not be impacted by this because there is no reason to lie when responding. D. It is very possible that…

Suppose you did an experiment with 3 groups and 16 subjects per group. The sample variances in the three groups were 14, 16, and 18. Using Tukey's test to compare the means, what would be the two-tailed probability for a comparison of the first mean (14) with the last mean (18)?

In a particular survey of internet users, 3575 respondents say that they use social networking sites and 1348 respondents say that they do not use social networking sites. What is the probability that a randomly selected person uses a social networking site?

The probability that a randomly selected person uses a social networking site i
