A paper company has about 50 paper mills distributed over 3 provinces. Each mill records specified
factors that contribute to its profitability. The company has classified the mills as Profitable and Non-
Profitable. They recorded paper weight produced as an indicator of profitability. That is,
X₁ = PAPER (weight in 10000 kilograms)
Y = PROF (1 = profitable and 0 = not profitable)

An aircraft emergency locator transmitter (ELT) is a device designed to transmit a signal in the case of a crash. Company A makes 80% of the ELTs, Company B makes 15% of them and Company C makes the other 5%. The ELTs made by Company A have a 7.8% rate of defects, the Company B ELTs have a 6.3% rate of defects and the Company C ELTs have 6.4% rate of defects. If a randomly selected ELT is tested and found to be defective, find is the probability that it was made by Company A? Give your answer to three decimal places.
Urgent Care is organized in to 4 department: Registration (Reg), Waiting (Wait), Treatment (Treat), and Payment & Check Out (PCO). For all
patients who receive treatment at the Urgent Care, the expected time (in minutes) per patient needed in each of the departments:
Reg.
Wait.
Treatment
PCO

3 or 2
All patients enter and register at the registration cubicle. After registering, 10% of the patients walk out without waiting and seeing the
physician for treatment. However, still they have to walk through the PCO & return the admissions slip. These patients need only 2 min at
PCO (instead of 3 min for the patients receiving treatment). No waiting and treatment time for patients who walk out.
Simulate the total time spent in the Urgent care for the second patient. Total time spent by Patient 2 at the Urgent Care is:
RN: 55

Over a one-month period, the first group received a low dosage of an experimental drug, the second group received a high dosage of the drug, and the third group received a placebo. The diastolic blood pressure of each participant was measured at the beginning and at the end of the period and the change in blood pressure was recorded.
