- SECTION 11.6: CONDITIONAL PROBABILITY ONLINE VERSION Two hundred patients who had either hip surgery or knee surgery were asked whether they were satisfied or dissatisfied with the results of their surgery. The responses are given in the table below: Satisfied Dissatisfied Total Surgery Knee Hip Total 70 25 95 90 15 105 160 40 200 1. Use the table above to answer the following questions. Express your answers as REDUCED FRACTIONS What is the probability that a person had hip surgery, given that they were satisfied? a. b. What is the probability that a person was dissatisfied, given that they had knee surgery? What is the probability that a person had knee surgery, given that they were dissatisfied? C. d. What is the probability that a person was dissatisfied, given that they had hip surgery?arrow_forwardType I and Type I l Errors. In Exercises 29–32, provide statements that identify the type I error and the type II error that correspond to the given claim. (Although conclusions are usually expressed in verbal form, the answers here can be expressed with statements that include symbolic expressions such as p = 0.1. The proportion of people who require no vision correction is less than 0.25.arrow_forwardRedo exercises 17 and 18 in section 8.1 of your textbook, about the small animal who lives in an area with woods and meadows, using the following data:If the animal is in the woods on one observation, then it is three times as likely to be in the woods as the meadows on the next observation. If the animal is in the meadows on one observation, then it is four times as likely to be in the meadows as the woods on the next observation.Assume that state 1 is being in the meadows and that state 2 is being in the woods. (A) If the animal is initially in the woods, what is the probability that it is in the woods on the next three observations? (B) If the animal is initially in the woods, what is the probability that it is in the meadow on the next three observations?arrow_forward

One student is selected at random. Find the following: a. The probability density function (pdf) of amount of time taken for the quiz. b. The probability that the student requires more than 50 minutes to complete the quiz. c. The probability that the student completes the quiz in a time between 35 and 40 minutes. d. The probability that the student requires at least 45 minutes to complete the quiz. e. The probability that the student completes the quiz exactly 52 minutes. f. Compute the expected time and the coefficient of variation to complete the quiz. B) Using 95% confidence, how large a sample should be taken to obtain a margin of error for the estimation of a population proportion of 0.065?
