THIS QUESTION WAS ANSWERED BEFORE BUT A-D. PLEASE ANSWER SECTION E.
There is no mass transit in Cedar Grove, so Letecia’s goats are
fascinated with buses and trains now that they live in SoCal. In
fact, they spend anywhere between 30 and 150 minutes each day on
some form of mass transit or other, and no length of time is any
more likely than any other.
a. Draw a graph of the distribution of the amount of time that any
of Letecia’s goats spends on mass transit in a day.
b. What is the probability that one of Letecia’s goats spends more
than two hours on mass transit in a day?
c. What is the probability that one of Letecia’s goats spends
exactly one hour on mass transit in a day?
d. What is the amount of time one of Letecia’s goats is expected to
spend on mass transit in a day? What is the standard
deviation?
e. Supposing that the amount of time a goat spends on mass transit
each day is independent. What would be the probability that a goat
would spend more than 23 complete days on mass transit over the
course of a year?
