. There is a fire sensor system in a building. In long series of experiments, it was found that the accuracy of the fire sensor system can be described as follows: • In the case of a fire, the sensor system will be activated with probability 0.97. • In a night without fire, the sensor system may be activated with probability 0.01. The probability of a fire in this specific area is founded 2/397 from the past data. The fire sensor system is activated. Find the probability that there was actually a fire.

A pharmaceutical company receives large shipments of aspirin tablets. The acceptance sampling plan is to randomly select and test 22 tablets, then accept the whole batch if there is only one or none that doesn't meet the required specifications. If a particular shipment of thousands of aspirin tablets actually has a 6% rate of defects, what is the probability that this whole shipment will be accepted? ... The probability that this whole shipment will be accepted is (Round to three decimal places as needed.)
29 percent of all Samsung cell phones are submitted for service while under warranty. Of these, 66 percent can be repaired, whereas the other 34 percent must be replaced with new units. If a company purchases 12 Samsung cell phones, what is the probability that exactly 2 will end up being replaced under warranty? What would the mean number of cell phones being replaced under warranty be? What would be the variance be for the cell phones being replaced by warranty?.
A psychology teacher teaches two statistics classes back-to-back, lecture L1 at 09:00 am and lecture CL1 at 10 am. Suppose the probability that the instructor gives a good L1 lecture is 0.25. If L1 lecture is good, then CL1 lecture is also good with probability 0.50. However, if L1 lecture is bad, then there is an 90% chance that CL1 lecture will also be bad. a) What proportion of the CL1 lectures are good? b) Suppose CL1 lecture was good. What is the probability that L1 lecture was also good? c) What is the probability that at least one lecture is good (i.e., either L1 lecture is good or CL1 lecture is good, or both)?
Apparently, depression significantly increases the risk of developing dementia later in lift (BBC News, July 6, 2010). In a recent study it was reported that 22% of those who had depression went on to develop dementia, compared to only 17% of those who did not have depression. Suppose 10% of all people suffer from depression. What is the probability of a person developing dementia? If a person has developed dementia, what is the probability that the person suffered from depression earlier in life?
According to Johns Hopkins data, the mortality rate of Covid-19 for the USA and the UK respectively 1.7% and 2.7%.It is expected that next week there will be 1,200,000 (1.2 million) and 238,000 Covid-19 cases for the US and the UK, respectively.Deaths in the USA and the UK assuming independent, Covid-19 for US and UK next week Find the probability that the total number of deaths is at least 27,000.Hint: Use the normal approximation to the binomial distribution.
A survey showed that 81% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight. If 20 adults are randomly selected, find the probability that no more than 1 of them need correction for their eyesight. Is 1 a significantly low number of adults requiring eyesight correction? The probability that no more than 1 of the 20 adults require eyesight correction is (Round to three decimal places as needed.)
A factory uses a specific machine to produce pieces. From previous data, we know that 97% of the time the machine is set up correctly. If this is the case, it produces 95% acceptable (non-defective) pieces. However, if it is not set up correctly, it produces only 40% of acceptable pieces Q23 Given that the selected piece is non-defective, what is the probability that the machine is set up correctly? Your answer should be in % and have two digits after the period. So, if your answer is 50.023%, enter 50.02. Your Answer:
