According to the Bureau of Transportation Statistics, 81.9 % of American Airlines flights were on time in 2017. Assume this percentage still holds true for American Airlines. For the next 46 flights from American Airlines, use the normal approximation to the binomial distribution. Determine the probability that 37, 38, 39, 40, or 41 flights will arrive on time.

According to the Bureau of Transportation Statistics, 81.9% of
American Airlines flights were on time in 2017. Assume this
percentage still holds true for American Airlines. For the next 46
flights from American Airlines, use the normal approximation to
the binomial distribution. Determine the probability that 34, 35,
36, or 37 flights will arrive on time.

American Airlines flights were on time in 2017. Assume this
percentage still holds true for American Airlines. For the next
44 flights from American Airlines, use the normal approximation
to the binomial distribution to complete parts a through d.
a.) Determine the probability that fewer than 34 flights will
arrive on time.
b.) Determine the probability that exactly 32 flights will
arrive on time.
c.) Determine the probability that 25, 26,...

American Airlines' flights from Chicago to Atlanta are on time
70 % of the time. Suppose 9 flights are randomly selected, and the
number on-time flights is recorded.
Round answers to 3 significant figures.
The probability that exactly 7 flights are on time is =
The probability that at most 3 flights are on time is =
The probability that at least 4 flights are on time is =

The survey by The Bureau of Labor Statistics American Time, showed that the time a person spends in the United States using a computer for entertainment varies greatly according to age. Individuals aged 75 years and older averaged 0.3 hrs (18 minutes) per day. Those aged 15 to 19 spent 1.0 hrs a day. If these times follow an exponential distribution find the proportion of each group that passes:
a) Less than 15 minutes a day using the computer to...

The Bureau of Labor Statistics’ American Time Use
Survey showed that the amount of time spent using a computer
for leisure varied greatly by age. Individuals age 75 and over
averaged 0.40 hour (24 minutes) per day using a computer for
leisure. Individuals ages 15 to 19 spend 1.1 hour per day using a
computer for leisure. If these times follow an exponential
distribution, find the proportion of each group that spends:
Less than 22 minutes per day using a...

According to a national statistics bureau, in 2000, 21.8% of
males living in the Southwest were retired exterminators. A
researcher believes that the percentage has increased since then.
She randomly selects 275 males in the Southwest and finds that 68
of them are retired exterminators. Test this researcher's claim at
the 2% level of significance.(Round to two decimal places)
(a) Critical Value:
(b) Test Score
(c) Construct a 98% confidence interval for the proportion of
retired exterminators. (Round to 2...

Suppose American Airlines quotes a flight time of 137 minutes
for its flights from Irvine, CA to DFW.
Suppose we believe that actual flight times are
uniformly distributed between 110 minutes and 160
minutes. Answer the following questions.
a. The probability density function between the range is defined
as f(x)= .
b. Compute the probability that a flight from Irvine, CA to DFW
will be more than 10 minutes late from its quoted time.
P=(X>147)=
c. Compute the probability that its...

1. The U.S. Department of Transportation reported that during
November, 83.4% of Southwest
Airlines’ flights, 75.1% of US Airways’ flights, and 70.1% of
JetBlue’s flights arrived on time (USA
Today, January 4, 2007). Assume that this on-time performance is
applicable for flights arriving at
concourse A of the Rochester International Airport, and that 40% of
the arrivals at concourse Aare
Southwest Airlines flights, 35% are US Airways flights, and 25% are
JetBlue flights.
a. An announcement has just been made...
