Suppose p denotes the probability of observing tails when an unfair coin is tossed once. Jack flipped the coin in order to estimate this probability and based on his flips, he found a 90% confidence interval for p to be (0.15,0.25). How many times did Jack toss the coin to construct this interval? O 36 O 6 O 174 O 106 O 96

Which of the following are criteria for a binomial probability experiment? Select all that apply. O A. There are two mutually exclusive outcomes, success or failure. B. The trials are independent. O C. The experiment is performed a fixed number of times. O D. The probability of success is different for each trial of the experiment. O E. The probability of success is the same for each trial of the experiment. O F. The experiment is performed until a desired number of successes is reached. O G. Each trial depends on the previous trial. O H. There are three mutually exclusive outcomes, arriving on-time, arriving early, and arriving late.

Refer to the sample data for pre-employment drug screening shown below. If one of the subjects is randomly selected, what is the probability that the test result is a false positive? Who would suffer from a false positive result? Why? Pre-Employment Drug Screening Results Positive test result Negative test result Drug Use Is Indicated Drug Use Is Not Indicated Subject Uses Drugs 42 11 Subject Is Not a Drug User 2 29 The probability of a false positive test result is (Round to three decimal places as needed.) Who would suffer from a false positive result? Why? O A. The person tested would suffer because he or she would be suspected of using drugs when in reality he or she does not use drugs. B. The employer would suffer because the person tested would not be suspected of using drugs when in reality he or she does use drugs. C. The person tested would suffer because he or she would not be suspected of using drugs when in reality he or she does use drugs. D. The employer would suffer…

Based on a survey, when 1009 consumers were asked if they are comfortable with drones delivering their purchases, 42% said yes. The probability of randomly selecting 30 of the 1009 consumers and getting exactly 24 who are comfortable with the drones is represented as 0+. What does 0+ indicate? Does 0 + indicate that it is impossible to get exactly 24 consumers who are comfortable with drones? Choose the correct answer below. O A. The probability 0+ indicates that the probability is a very small positive value. It indicates that the event is likely. O B. The probability 0+ indicates that the probability is a very small positive value. It indicates that the event is impossible. O C. The probability 0+ indicates that the probability is zero. It indicates that the event is impossible. O D. The probability 0+ indicates that the probability is a very small positive value. It indicates that the event is possible, but very unlikely.
