Question

it
is estimated that only 68% of drivers wear their safety belt.

Part A: what is the probability that exactly 3 drivers are
wearing their safety belt if a police officer pulls over five
drivers?

Part B: what is a probability the next driver wearing their
safety belt that the police officer pulls over the fifth
driver?

Answer #1

t is estimated that only 68% of drivers wear their safety
belt.
Part A: What is the probability that exactly 3
drivers are wearing their safety belts if a police officer pulls
over five drivers?
Part B: What is the probability the next driver
wearing their safety belt that the police officer pulls over is the
fifth driver?

Police estimate that 81 % of drivers wear their seatbelts. They
set up a safety roadblock, stopping cars to check for seatbelt
use. If they stop 100 cars, what is the probability they find at
least 16 drivers not wearing their seatbelts? Use a Normal
approximation. (Type an integer or a decimal rounded to four
decimal places as needed.)

Assume that police estimate that 18% of drivers do not wear
their seatbelts. They set up a safety roadblock, stopping cars to
check for seatbelt use. They stop 40 cars during the first hour. a.
Find the mean, variance, and standard deviation of the number of
drivers expected not to be wearing seatbelts. Use the fact that the
mean of a geometric distribution is mu equals StartFraction 1 Over
p EndFraction and the variance is sigma squared equals
StartFraction q...

A recent Maryland highway safety study found that in 77% of all
accidents the driver was wearing a seatbelt. Accident reports
indicated that 92% of those drivers escaped serious injury (defined
as hospitalization or death), but only 63% of the nonbelted drivers
were so fortunate.
Draw a tree diagram.
a. What is the probability that a person was seriously
injured?
b. What is the probability that given a driver was seriously
injured, they were not wearing a seatbelt?

1 a.) Suppose that only 25% of all drivers come to a complete
stop at an intersection having flashing red lights in all
directions when no other cars are visible. What is the probability
that, of 15 randomly chosen drivers coming to an intersection under
these conditions, exactly 3 will come to a complete stop?

Part 1
The three most popular options on a certain type of new car are
a built-in GPS (A), a sunroof (B), and an automatic transmission
(C). If 48% of all purchasers request A, 59% request B, 74% request
C, 68% request A or B, 85% request A or C, 83% request B or C, and
90% request A or B or C, determine the probabilities of the
following events. [Hint: "A or B" is the event that at least...

1. Is NASCARs main goal to maximize profits? If not, what is
their major goal? Is there a tradeoff involved here?
2. Is the motivation for the actions described in the NYT
article (safety changes, blackbox data collection) connected to
their goal? Explain.
3. If people tune in to see crashes (Nascar fans love crashes
the way hockey fans love fights; when you watch the Speed Channel's
edited replays of Nascar races, the plot is always the same: green
flag,...
