Question

Today, the waves are crashing onto the beach every 5.3 seconds. The times from when a person arrives at the shoreline until a crashing wave is observed follows a Uniform distribution from 0 to 5.3 seconds. Round to 4 decimal places where possible.

- The mean of this distribution is_______
- The standard deviation is_______
- The probability that wave will crash onto the beach exactly 2.4
seconds after the person arrives is P(
*x*= 2.4) = _______ - The probability that the wave will crash onto the beach between
0.8 and 1.4 seconds after the person arrives is P(0.8 <
*x*< 1.4) = _______ - The probability that it will take longer than 3.66 seconds for
the wave to crash onto the beach after the person arrives is
P(
*x*≥≥ 3.66) = _______ - Find the minimum for the upper quartile. _______ seconds.

Answer #1

Today, the waves are crashing onto the beach every 5.3 seconds.
The times from when a person arrives at the shoreline until a
crashing wave is observed follows a Uniform distribution from 0 to
5.3 seconds. Round to 4 decimal places where possible.
The standard deviation is ______ it is not (1.529) the mean is
2.65
The probability that it will take longer than 3.66 seconds for
the wave to crash onto the beach after the person arrives is
P(x...

Today, the waves are crashing onto the beach every 6 seconds.
The times from when a person arrives at the shoreline until a
crashing wave is observed follows a Uniform distribution from 0 to
6 seconds. Round to 4 decimal places where possible. a. The mean of
this distribution is b. The standard deviation is c. The
probability that wave will crash onto the beach exactly 3.3 seconds
after the person arrives is P(x = 3.3) = d. The probability...

Today, the waves are crashing onto the beach every 4.4 seconds.
The times from when a person arrives at the shoreline until a
crashing wave is observed follows a Uniform distribution from 0 to
4.4 seconds. Round to 4 decimal places where possible. e. The
probability that it will take longer than 1.58 seconds for the wave
to crash onto the beach after the person arrives is P(x > 1.58)
= f. Suppose that the person has already been standing...

1)Today, the waves are crashing onto the beach every 5.6

possible.
a. The mean of this distribution is
b. The standard deviation is
c. The probability that wave will crash onto the beach exactly
0.4 seconds after the person arrives is P(x = 0.4)
=
d. The probability...

A bus comes by every 11 minutes. The times from when a person
arives at the busstop until the bus arrives follows a Uniform
distribution from 0 to 11 minutes. A person arrives at the bus stop
at a randomly selected time. Round to 4 decimal places where
possible. The mean of this distribution is 5.50 Correct The
standard deviation is 3.1754 Correct The probability that the
person will wait more than 4 minutes is 0.6364 Correct Suppose that
