A survey showed that 80% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight. If 16 adults are randomly selected, find the probability that at least 15 of them need correction for their eyesight. Is 15 a significantly high number of adults requiring eyesight correction? The probability that at least 15 of the 16 adults require eyesight correction is (Round to three decimal places as needed.)

A certain bridge in Cebu is being re-constructed. The civil engineers would like to consider the number of heavy-duty vehicles that pass through that certain bridge in re-designing. The industrial engineers are tasked to do the job in finding the probability that certain number of heavy-duty vehicles pass through the bridge in a specific period of time. The IEs collected the data below. The IE would like to know if queuing theory is applicable in simulating the number of heavy-duty vehicles that pass through the bridge. One condition of using queuing theory is that the data must be Poisson distributed. Test at 1% level of significance if the data is collected by the IE is Poisson distributed.
Traffic engineers are investigating the high rate of fatal accidents at a lighted city intersection. They discover that 26% of the cars that are within 200 feet of the intersection when the light turns red pass through the red light without stopping. Suppose two cars are now within 200 feet of the Intersection and the light turns red. Assuming that drivers behave independently of one another. What is the probability that both drivers pass through the red light without stopping? (Please do not round your answer).
People with restless leg syndrome have a strong urge to move their legs to stop uncomfortable sensations. People with fibromyalgia suffer pain and tenderness in joints throughout the body. A recent study indicates that people with fibromyalgia are much more likely to have restless leg syndrome than people without the disease.1 The study indicates that, for people with fibromyalgia, the probability is 0.33 of having restless leg syndrome, while for people without fibromyalgia, the probability is 0.03. About 2% of the population has fibromyalgia.Create a tree diagram from this information and use it to find the probability that a person with restless leg syndrome has fibromyalgia.Round your answer to three decimal places.
The prevalence of glaucoma in elderly people among high-risk populations within a city is approximately 5%.

A company did a study of available vacation time for their staff employees over the past years. They determined the probability a staff employee selected at random has 2 weeks’ vacation was 45%, 1 week vacation 10%, 3 weeks’ vacation 20%, and more than 3 weeks’ vacation was 25%. The company randomly selects 20 employees. What is the probability that out of the 20 selected, at least 2 workers have 1 week vacation time?
