Answer #1

The time of travel from a person's apartment to the bus station
follows a uniform distribution over the interval from 10 to 30
minutes. If he/she leaves home at 8:00 AM, what is the probability
that he/she will get to the station between 8:30 and 8:35 AM?

A bus arrives at a station every day at a random time between

The average number of passengers arriving at the Bus Station in
Lancaster on Tuesday between 8:00 and 9:00 is 900.
1.To model this random phenomenon, which probability
distribution is most suitable? Assume that passengers arrive at
random at a constant rate throughout the hour.
2.Using the most suitable probability distribution, consider the
following three statements:
I. There are 15 passengers arriving every minute on average
II. The standard deviation of the number of passengers arriving
in an hour is 30...
