Of all people in one population, 21% have high blood pressure and 36% are overweight. In addition, 42% of people who are overweight also have high blood pressure. Let H represent the event that a person has high blood pressure, and O represent the event that a person is overweight. In each part of this question, you must first express each probability in terms of the events H and O and justify any computation through the use of a formula. (a) Express each of the three probabilities listed above in terms of the events H and O. (b) Are H and O independent events? Explain your answer using only the probabilities stated in part (a). (c) What proportion of all people are not overweight? (d) What is the probability that a randomly selected person will have high blood pressure and be overweight? Are H and O mutually exclusive events? Explain. (e) What is the probability that a randomly selected person will have at least one of these two conditions? (f) What proportion of all people have high blood pressure but are not overweight? (g) If a person has high blood pressure, what is the probability they are also overweight?

One with a systolic blood pressure greater than 129 is considered to have high blood pressure. A study recorded the systolic blood pressures of 14 randomly selected Americans, which yielded a mean of 131.57 with standard deviation 15.88. Conduct a hypothesis test to see if you can say that Americans, on average, have high blood pressure. 1.Write the hypotheses for this test. 2.What is the test statistic? 3.What is the p-value? 4.Using α = 0.05, decide whether or not to...

Assume X = systolic blood pressure of a healthy adult aged 21-45 where X is assumed to be normally distributed with  = 120 and σ = 20. a. Find the probability that a randomly selected person from this population has systolic blood pressure less than 140, ie find P(X < 140). b. If 10% of the population have "high" systolic blood pressure, find the borderline point between "normal" and "high", ie find x0 such that P(X > x0) =...
