American adults spend an average of 11 (standard deviation of 2.5 hours) hours per day watching, reading, listening to or simply interacting with media, according to a new study by market-research group Nielsen. A US adult is randomly selected, what is the probability that: (a) The person spends less than 16 hours? (b) The person spends more than 6 hours? (c) The person spends between 4 hours and 15 hours? (d) The person spends less than 3 or more than 15 hours? (e) The person spends exactly 10 hours?

Among 9318 cases of heart pacemaker malfunctions, 393 were found to be caused by firmware, which is software programmed into the device. If the firmware is tested in 3 different pacemakers randomly selected from this batch of 9318 and the entire batch is accepted if there are no failures, what is the probability that the firmware in the entire batch will be accepted? Is this procedure likely to result in the entire batch being accepted? The probability is This procedure is V to result in the entire batch being accepted. (Round to three decimal places as needed.)
Among 8736 cases of heart pacemaker malfunctions, 373 were found to be caused by firmware, which is software programmed into the device. If the firmware is tested in 3 different pacemakers randomly selected from this batch of 8736 and the entire batch is accepted if there are no failures, what is the probability that the firmware in the entire batch will be accepted? Is this procedure likely to result in the entire batch being accepted? The probability is enter your response here. This procedure is ▼ likely unlikely certain to result in the entire batch being accepted. (Round to three decimal places as needed.)
Human pregnancies of healthy singleton fetuses (i.e., excluding pregnancies with early-term complications or miscarriages, and multiple births) are normally distributed with a mean of 266 days and a standard deviation of 13 days. What is the probability that a baby is born between 250 and 275 days? If we stipulate that a baby is premature when born at least 3 weeks early, what is the probability a randomly selected baby is premature? If we stipulate that a baby is overdue when born more than 2 weeks after the expected date, what is the probability a randomly selected baby is overdue?

1% of the computers at UMD have been compromised by a cyberattack. DiT has an intrusion detection system (IDS) that raises an alert 97% of the time if a computer is compromised, and does not raise an alert 95% of the time if a computer is not compromised. What is the probability that the IDS raises an alert? number (rtol=0.01, atol=D0.0001) What is the probability that the computer has not been compromised when the IDS raises an alert? number (rtol=0.01, atol=D0.0001)

Among 6464 cases of heart pacemaker malfunctions, 341 were found to be caused by firmware, which is software programmed into the device. If the firmware is tested in 3 different pacemakers randomly selected from this batch of 6464 and the entire batch is accepted if there are no failures, what is the probability that the firmware in the entire batch will be accepted? Is this procedure likely to result in the entire batch being accepted? The probability is 0.850 . This procedure is likely to result in the entire batch being accepted.

An air traveler from Istanbul to Ankara have two options on Turkish Airlines: a 190 TL fare with a50% cancellation penalty, and a 250 TL fare with a 10% penalty. Assume that the probability of travelercanceling the trip is p.• What is the probability distribution for the amount of money Turkish airline is going to earn for the190 TL option? What is the same distribution for the 250 TL option? (Answer in terms of p).• What is the expected amount of money Turkish Airlines is going to earn under two options?• For what values of p does the 250 TL option yield lower expected price? What does this outcomesuggest about the preferable option for a typical traveler?
Among 7425 cases of heart pacemaker malfunctions, 425 were found to be caused by firmware, which is software programmed into the device.
