Acertain flight arrives on time 86 percent of the time. suppose 154 flights are randomly selected. use the normal approximation to the binomial to approximate the probability that (a) exactly 136 flights are on time. (b) at least 136 flights are on time. (c) fewer than 137 flights are on time. (d) between 137 and 146, inclusive are on time. (a) p(136)equals=nothing (round to four decimal places as needed.)

Step-by-step explanation:

Let X be no of flights that arrives on time 86 percent of the time. Suppose 154 flights are randomly selected

Mean = np and variance = npq

Hence X is N(132.44,4.31)

Without continuity correction if we do P(X=136) =0

with cont correction

a)P(x=136) =

b)P(atleast136)=

c)

d)

false.

step-by-step explanation:

false.

cavalieri's principle makes that statement about the volumes, not about the areas.

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.
