HypertensionA national study found that treating people appropriately for high blood pressure reduced their overall mortality by 20%. Treating people adequately for hypertension has been difficult because it is estimated that 50% of hypertensives do not know they have high blood pressure, 50% of those who doknow are inadequately treated by their physicians, and 50% who are appropriately treated fail to follow this treatment by taking the right number of pills.USE SALT(a) What is the probability that among 10 true hypertensives at least 50% are being treated appropriately and are complying with this treatment? (Round your answer to four decimal places.)(b) What is the probability that at least 8 of the 10 hypertensives know they have high blood pressure? (Round your answer to four decimal places.)(c) If the preceding 50% rates were each reduced to 35% by a massive education program, then what effect would this change have on the overall mortality rate among true hypertensives; that is, would the mortality rate decrease and, if so, what percentage of deaths among hypertensives could beprevented by the education program? (Round your answer to two decimal places.)The overall mortality rate among hypertensives would be reduced by%.

It is known that the use of banned drugs can contribute to mental illness. The minister of health wants to put a cost to this disaster and request that you take a study. In Barbados 40% of mentally ill blame their illness on drugs. Without previous knowledge in Jamaica we assume that this is the same proportion here. You selected a random sample of 12Bellevue patients to review. What is the probability that 6 patients used the drugs that caused their illness.
An article was published recently suggesting that persons who exercise regularly can reduce their risk of major clinical events (e.g. diabetes, cardiovascular disease) by up to 50% in some instances. It is believed that only 30% of adult Americans exercise on a regular basis. If eight adult Americans are analyzed, what is the probability that less than half of them exercise regularly? For some reason, I keep coming out with the wrong numbers.
Teenagers who do not sleep well or long enough may have a higher risk of raised blood pressure, which could lead to cardiovascular disease later in life. The odds of raised blood pressure increase 3.5 times for those who have trouble falling asleep at night or who wake up too early and 2.5 times for those with sleeping periods of fewer than 6.5 hours. A health psychologist is interested in studying teenagers who have diastolic blood pressure scores in the top 20%. Diastolic blood pressure scores for teenagers follow a normal distribution with μ = 72 and σ = 10. Use the Distributions tool to help answer the questions that follow. The minimum z-score necessary to be in the top 20% of the diastolic blood pressure distribution is z =0.842 . Use this z-score to determine X, the corresponding diastolic blood pressure score. X = 80.42 This score, X, is the 80th percentile of diastolic blood pressure scores among teenagers. The percentile rank of this score is 80%…
Apparently, depression significantly increases the risk of developing dementia later in lift (BBC News, July 6, 2010). In a recent study it was reported that 22% of those who had depression went on to develop dementia, compared to only 17% of those who did not have depression. Suppose 10% of all people suffer from depression. What is the probability of a person developing dementia? If a person has developed dementia, what is the probability that the person suffered from depression earlier in life?

Dementia is the loss of the intellectual and social abilities severe enough to interfere with judgment, behavior, and daily functioning. Alzheimer’s disease is the most common type of dementia. Researchers explored the experience and struggles of people diagnosed with dementia and their families. Research has shown that the mean age at diagnosis of all people with early-onset dementia is 55 years, and the population standard deviation is 6.8 years.yt What is the probability a single person will be diagnosed with early-onset dementia is less than 50 years? Do we know if the sample mean of samples of size 20 is normally distributed or not? Explain.
Is the expected value (mean) of the probability distribution of a random variable always one of the possible values of x from the distribution ? Explain
