A radar unit is used to measure the speed of cars on a highway
during rush hour traffic. The speeds of individual cars are
normally distributed with a mean of 55 mph and a standard deviation
of 3.2 mph. Find the probability of the following events:
(a) A car traveling faster than average.
(b) A car traveling over 65 mph
(c) A car traveling between 48 and 50 mph.

A police car on the side of the road (at rest) uses a radar gun
to catch speeders as they approach it. The frequency the radar gun
emits is 8 x 109 Hz and the speed limit is 65 mi/hr.
a)What is the frequency of the radio wave that the car "sees"?
Since they cant really see:)
b)What is the frequency of the reflected radio wave that is picked
up by the receiver inside the radar gun?

A police car sounding a siren with a frequency of 1550 Hz is
traveling at 130 km/h .
What frequencies does an observer standing next to the road hear
as the car approaches? As it recedes?
What frequencies are heard in a car traveling at 90.0 km/h in
the opposite direction before and after passing the police car? For
both approaching and receding
The police car passes a car traveling in the same direction at
80.0 km/h. What two frequencies...

The Arizona Highway Patrol wants to estimate what proportion of
all drivers exceed the 75 mph speed limit on a stretch of Rt. 40 on
the Arizona side of the state border with New Mexico. For a sample
of 1000 vehicles on a given day, 413 exceeded the speed limit.
Based on this sample, construct a 95% confidence interval for the
percent of vehicles that exceed the speed limit.
