p = 83%

n = 222

Can we say that the sampling distribution of p^ is approximately normal? Yes

Because np = ____________which is ___________

n(1 - p) =_______________ which is ____________

and N = ____________ which is (or is assumed to be) ___________

Note: if N is unknown, type 1000000 in for its value.

c) What is the probability that at least 90% of the randomly selected booked passengers showed up on time?

Fill in below with the correct random variable and inequality symbol in the probability statement.

Round final answer to 4 decimal places.

P(p X 0.9) = _______________

d) Is 79% an unusually low percentage of booked passengers that show up on time for their flight in a sample of 222?

• Since P(p X 79%) = _____________ which is > ______________, 79% Select an answer is not is an unusually low percentage of booked passengers that show up on time for their flight in a sample of 222
