Anthony has just received Covid-19 test results from a patient named Melania. The accuracy of thetest is as follows: the probability the test will be positive if Melania has Covid-19 is p, and theprobability the test will be positive if Melania does not have Covid-19 is q. The proportion of thepopulation that has Covid-19 is 7. The test comes back positive. Anthony has no information aboutMelania's symptoms. (For reasons he does not understand.)Problem 3cWhat value of y would result in the simple model of base-rate neglect we learned in class?67O 33O 25Question 24Problem 3dIf p = .95, q = .05, and r = .1, what must be the value of y if Anthony believes that theprobability Melania has Covid-19 is .9?O 3.214O 5O 1.05O 3.57

A coin is tossed 4 times and gives four heads in a row. You say “I guess that the fifth toss will result into a head with a probability of 1.”
The accompanying table shows the results from a test for a certain disease. Find the probability of selecting a subject with a negative test result, given that the subject has the disease. What would be an unfavorable consequence of this error? The individual actually O had the disease Yes No Positive 334 Negative 13 1176 EEE .E The probability is (Round to three decimal places as needed.) What would be an unfavorable consequence of this error? A. The test would be shown to be not effective. OB. The subject would experience needless stress and additional testing. Gradebo O C. The subject would not receive treatment and could spread the disease. Sco O D. The test would be shown to be not reliable. see scor
Consider the experiment: You ask someone two multiple-choice questions. Each question could be answered with Yes (Y), No (N), or Don't Know (D). (For example, if you ask someone these two questions, they could answer Yes to both of them, or Yes to the first one and Don't Know to the second one, etc.) Let A be the event that the person answers Yes to at least one question, and Let B be the event that the person answers No to the second question. How many elements are in the sample space? What elements are in A ∩ B? What elements are in A ′?
Drivers were surveyed about their driving styles and the type of vehicle they drive. The results are summarized in the two-way table. Attentive Defensive Eco-friendly Sedan 24 20 10 SUV 18 13 7 Motorcycle 12 5 7 Truck 6 10 4 The equation 0.4 0.397 is the mathematical justification proving which of the following statements? The events driving a sedan and driving in an attentive style are approximately independent because P(attentive | sedan) = P(attentive). The events driving a sedan and driving in an attentive style are not independent because P(sedan | attentive) = P(sedan). ༤ Ⓒ The events driving a sedan and driving in an attentive style are approximately independent because P(sedan | attentive) = P(sedan).
