The time it takes a person to wash the dishes is uniformly distributed between 7 minutes and 12 minutes. What is the probablity that a randomly selected event of washing dishes will take a person between 8 and 10 minutes? Round your answer accurate to two decimal places.
A survey of 704 randomly selected students was conducted to determine student opinion about taking full- semester classes, 12-week classes, or eight-week classes. The survey reported that 25% of the students surveyed preferred 12-week sections. The survey estimate had a margin of error of 2 percentage points. A margin of error is reported because The people doing the survey may have recorded results incorrectly. Students may intentionally respond incorrectly. Students may misunderstand the survey questions. Sample proportions vary from sample...
Suppose the time it takes a barber to complete a haircuts is uniformly distributed between 8 and 22 minutes, inclusive. Let X = the time, in minutes, it takes a barber to complete a haircut. Then X ~ U (8, 22). Find the probability that a randomly selected barber needs at least 14 minutes to complete the haircut, P(x > 14) (answer to 4 decimal places)
Bus wait times are uniformly distributed between 8 minutes and 24 minutes. The unshaded rectangle below with area 1 depicts this. The shaded rectangle depicts the probability that a randomly selected bus wait time will be between 11 and 23 minutes. 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 Preview (Round answer to at least 4 Find the probability that a person waits between 11 and 23? decimal places)
The time it takes a student to finish a chemistry test is uniformly distributed between 50 and 70 minutes. What is the probability density function for this uniform distribution? Find the probability that a student will take between 40 and 60 minutes to finish the test. Find the probability that a student will take no less than 55 minutes to finish the test. What is the expected amount of time it takes a student to finish the test? What is...
Air-USA has a policy of booking as many as 24 persons on an airplane that can seat only 22. Past studies have revealed that only 88% of the booked passengers actually arrive for the flight.) Find the probability that if Air-USA books 24 persons, not enough seats will be available. prob - Is this probability low enough so that overbooking is not a real concern for passengers if you define unusual as 5% or less Ono, it is not low...
