10. In an experiment. college students were given eit MW her four quarters or a $1 bill and the y could either keep the money or spend it on gum. The results are summarized in the table. Complete parts (a) through (c) below. Students Given Four Quarters Students Given a $1 Btlt a. Find the probability of randomly selecting a student who spent the money. given that the student was given four quarters. The probability is . (Round to three decimal places as needed.) b. Find the probability of randomly selecting a student who kept the money, given that the student was given four quarters. The probability is . (Round to three decimal places as needed.) c. What do the preceding reSults suggest? {:1 A. A student given four quarters is more likely to have spent the money than a student given a $1 bill. {:3 B. A student given four quarters is more likely to have spent the money. C3 C. A student given four quarters is more likely to have kept the money. Ci D. A student given four quarters is more likely to have kept the money than a student given a $1 bill. The table below displays results from experiments with polygraph instruments. Find the positive predictive value for the test. That is. nd the probability that the subject lied. given that the test yields a positive result Did the Subject Actually Lie? No (Did Not Lie) Yes (Lied) Positive test results 17 4'1 Negative test results 33 12 The probability is . (Round to three decimal places as needed.)
