6. Trisomy 21, also called Down syndrome, is caused by having a third copy of the 21*tchromosome. The triple test is one of many tests that a pregnant parent can take to see iftheir developing fetus has Trisomy 21. The triple test detects Trisomy 21 when it is present60% of the time. This means it has a false negative rate of 40%. The triple test gives a falsepositive 5% of the time (when the fetus does not have trisomy 21). The probability that afetus has trisomy 21 is 0.001a. Ifa prepnant parent takes a triple test, what is the probability that they will get positiveresultb. If a pregnant parent has already received a positive triple test result, what is the probabilitythat the developing fetus has Trisomy 21

According to a study 55% of all males between the ages of 18 and 24, live at home. (unmarried college students living in a dorm, are counted as living at home.) suppose that a survey is administered and 141 of 246, respondents indicated that they live at home. A. Use the normal approximation to the binomial to approximate the probability that at least 141 respondents live at home. B. Do the results from part A contradict the study?

A weighted die has probability 0.102 of landing on a 6. If you roll the die until you get a 6 for the first time, what is the expected number of rolls it will take?
A chi-square test is conducted to determine if a standard 6-sided die is weighted. If the die is to be randomly tossed 400 times, how many times would you expect the number 1 to show on the die?
A new medical test has been designed to detect the presence of the mysterious Brainlesserian disease. Among those who have the disease, the probability that the disease will be detected by the new test is 0.7. However, the probability that the test will erroneously indicate the presence of the disease in those who do not actually have it is 0.04. It is estimated that 18% of the population who take the test have the disease. If the test is administered to an individual is positive, what is the probability that the person actually has the disease?
There are 4 red balls, 6 blue balls and 2 white balls in a bag. Suppose on every single turn, yourandomly select a ball, see the color of it and put it back in the bag.

What is the variance of the number of turns required to get one blue ball?
A new medical test has been designed to detect the presence of the mysterious Brainlesserian disease. Among those who have the disease, the probability that the disease will be detected by the new test is 0.82. However, the probability that the test will erroneously indicate the presence of the disease in those who do not actually have it is 0.08. It is estimated that 18 % of the population who take this test have the disease. If the test administered to an individual is positive, what is the probability that the person actually has the disease?
Jim is a 60-year-old male in reasonably good health. He wants to take out a $50,000 term (that is, straight death benefit) life insurance policy until he is 65. The policy will expire on his 65th birthday. The probability of death in a given year is provided by the Vital Statistics Section of the Statistical Abstract of the United States (116th edition) X=age 60 61 62 63 64 P(death at this age) 0.01191 0.01292 0.01396 0.01503 0.011613 Jim is applying to Big Rock Insurance Company for his term insurance policy. What is the probability that Jim will die in his 60th year? Using this probability and the $50,000 death benefit, what is the expected cost to Big Rock Insurance? Repeat part (a) for years 61, 62, 63, and 64. What would be the total expected cost to Big Rock Insurance over the years 60 through 64? If Big Rock Insurance wants to make a profit of $700 above the expected total cost paid out for Jim’s death, how much should it charge for the policy?…
