- An online customer service department estimates that about 15 percent of callers have to wait more than 8 minutes to have their calls answered by a person. The department conducted a simulation of 1,000 trials to estimate the probabilities that a certain number of callers out of the next 10 callers will have to wait more than 8 minutes to have their calls answered. The simulation is shown in the following histogram. Based on the simulation, what is the probability that at most 2 of the next 10 callers will have to wait more than 8 minutes to have their calls answered?Just before a city referendum on a school budget, a local newspaper polls 450 voters in an attempt to predict whether the budget will pass. Suppose that, unknown to everyone, the budget actually has the support of 52% of the voters. What is the probability the newspaper's sample will lead the newspaper to predict defeat of the referendum, that is, what is the probability that the newspaper's sample results in a sample proportion p̂ less than 0.50 in favor of the referendum?The manufacturing of semiconductor chips produces 2% defective chips. Assume that the chips are independent and that a lot contains 1000 chips. Approximate the following probabilities: (a) More than 25 chips are defective. (b) Between 20 and 30 chips are defective.
- The probabilities are 0.4, 0.2 and 0.3 and 0.1, respectively, that a student uses LAN,Wifi, Prepaid Data, or Hotspot for internet connection. What is the probability thatamong 10 randomly selected students, 2 use LAN, 4 use Wifi, 3 use prepaid data,and 1 uses Hotspot for their internet connection?HI! HELP ME WITH THIS PLEASE. THANK YOU VERY MUCH! The following hybrids are produced when white snowy owls are mated with brown barn owls: white barn owls, brown snowy owls, white snowy owls, and brown barn owls. The probabilities for each are 1/5, ¼, 9/20, and 1/10, respectively. If 9 owls are selected from this batch, find the probability that 2 are brown barn owls, 3 are white snowy owls, 1 is a brown snowy owl, and 3 are white barn owls.A hospital reports that two patients have been admitted who have contracted Crohn's disease. Suppose our experiment consists of observing whether each patient survives or dies as a result of the disease. The simple events and probabilities of their occurrences are shown in the table (where S in the first position means that patient 1 survives, D in the first position means that patient 1 dies, etc.). Simple Events Probabilities SS 0.52 SD 0.20 DS 0.14 DD 0.14 Find the probability that both patients survive.
- 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. Q22 A piece produced by the machine is selected. What is the probability that the selected piece is non-defective? Your answer should be in % and have two digits after the period. So, if your answer is 50.002%, enter 50.00. Your Answer:Two valleys are sometimes infected with tree rot. Suppose valley 1 is infected with probability 45%, valley 2 is infected with probability 60%, and the probability that at least one is infected is 85%. Suppose tree rot is observed in valley 2. What is the probabil- ity that valley 1 is also infected? Your answer should be a percentage (without the percent sign).If my z score is 3.125, and the question asks for the probability that X is less than a number, would the probability be unusual?? Because wouldn't that be saying that there is a 99% probability than X is less than 23, therefore NOT making it an unusual event?
- A certain group of women has a 0.06% rate of red/green color blindness. If a woman is randomly selected, what is the probability that she does not have red/green color blindness?It is found that a certain pharmaceutical cures symptoms in 35% adults. If 500 people take the pharmaceutical, what is the probability 200 or more adults have their symptoms cured? What is the expected number of people with symptoms cured?
