Suppose a COVID-19 is 85% sensitive and 82% specific. That is, the testwill produce 85% true positive results for those that have the virus and82% true negative results for those who do not. Suppose that 3.3% ofpeople actually have the virus. If a randomly selected individual testsnegative, what is the probability he or she does not have the virus?YOUR ANSWER SHOULD BE BETWEEN O AND 100 AND ROUNDED TO 4DECIMAL PLACES.(e.g. 59.5321 would be 59.5321%)

Let us define some events A : a person has the virus. B : a person does not have the virus. E : a…

Physicians at a clinic gave what they thought were drugs to 960960 asthma, ulcer, and herpes patients. Although the doctors later learned that the drugs were really placebos, 5252 % of the patients reported an improved condition. Assume that if the placebo is ineffective, the probability of a patients condition improving is 0.490.49. For the hypotheses that the proportion of improving is 0.490.49 against that it is >0.49>0.49, find the p-value. p=p=
A study by a reputable research organization found that when presented with prints from the same individual, a fingerprint expert will correctly identify the match 91% of the time. In contrast, a novice will correctly identify the match 77% of the time. Consider a sample of seven different pairs of fingerprints, where each pair is a match. Complete parts a and b below. a. What is the probability that an expert will correctly identify the match in all seven pairs of fingerprints? The probability is enter your response here. (Round to four decimal places as needed.) b. What is the probability that a novice will correctly identify the match in all seven pairs of fingerprints? The probability is enter your response here. (Round to four decimal places as needed.)
Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 94 people in the 18-21 age bracket and finds that 80 of them respond and 14 refuse to respond. When 265 people in the 22-29 age bracket are contacted, 241 respond and 24 refuse to respond. Assume that 1 of the 359 people is randomly splected. Find the probability of getting someone in the 22-29 age bracket or someone who refused to respornd. Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol. P(22-29 or refused) % %3D (Hint: It might be helpful to organize the data into a table first.)

a) The proportion of people in a given community who have Covid- 19 infection is 0.005. A test is available to diagnose the disease. If a person has Covid-19, the probability that the test will produce a positive signal is 0.99. If a person does not have the Covid-19, the probability that the test will produce a positive signal is 0.01. if a 2 person tests positive, what is the probability that the person actually has the Covid-19 infection? i. Which model will best be good for solving the above problem and why? ii. In your own words, comment on the types of events you see in the problem and name them. b) 30% of people who seek psychotherapy will recover from their symptoms irrespective of whether they receive treatment. A research finds that a particular type of psychotherapy is successful with 45 out of 100 clients.
