What is the expected value for the number of defective LCD

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 84% of the booked passengers actually arrive for the flight.) What is the expected number of passengers to arrive for the flight? Expected number of passengers = (please round to two decimal places) Find the probability that if Air-USA books 24 persons, not enough seats will be available. prob = (please round to four decimal places) Is this probability low enough so that overbooking is not a real concern for passengers if you define unusual as 5% or less? no, it is not low enough to not be a concern O yes, it is low enough not to be a concern What about defining unusual as 10% or less? O yes, it is low enough not to be a concern no, it is not low enough to not be a concern

In a cafe, the proportion of people who order coffee with their lunch is 0.9. A simple random sample of 144 patrons of the restaurant is taken. What is the expected value of the sample proportion? E(P) - What is the standard deviation (standard error) of the sample proportion P? Op What is the shape of the sampling distribution of P ?(just write the name: Normal, not normal, skewed, bimodal, uniform, etc. for instance) What is the probability that the proportion of people who will order coffee with their meal is between 0.85 to 0.875? (Round to two place decimal)

UNKNOWN STANDARD DEVIATION
