The demand for water from a certain city (in millions of
gallons) follows an exponential distribution with a lambda =
1/8.
A. If water resource capacity is 10 million gallons. What is
the probability of in one day any supplies are insufficient?
B. In the next ten days, what is the probability that we will
have water shortages in exactly two days?
C. If an inspector arrives, and every day checks for water
shortages, how many days of average will...

The water demand of a certain city (in millions of gallons)
follows an exponential distribution with a lambda = 1/4. If the
capacity of water resources is 10 million gallons.
a. What is the probability of supplies being insufficient on any
given day?
b. In the next ten days, what is the probability that we have
water shortages in exactly two days?
c. If an inspector arrives, and every day checks for water
shortages, how many days on average will...

Several years ago, a group of Honda Dealerships determined that
the average amount of days automobiles stay on dealers' lots was
equal to 22.1 days. They now believe that the mean time has changed
and would like to test their belief at a significance level of
0.05. Results of a sample of 50 cars on various lots can be found
in the file Honda Hypothesis Test. Use this information to answer
the next several questions and ultimately decide whether or...

An investment analyst is interested in examining the long run
relationship between the
3-month (91 days) Treasury bill (TB) rate and 6-month (182)
Treasury bill rate. Data on
these series were obtained from the Bank of Ghana website, spanning
from January, 2006,
to November, 2017.
Some preliminary tests were performed on the data and their outputs
are given below:
CASE 1:
Augmented Dickey-Fuller Test on the 3-month TBill rate
series.

2. Two ride-sharing companies, A and B, provide service for a
certain city. A random sample of 52 trips made by Company A and a
random sample of 52 trips made by Company B were selected, and the
number of miles traveled for each trip was recorded. The difference
between the sample means for the two companies
(A−B) was used to construct the 95 percent confidence interval
(1.86,2.15).
Which of the following is a correct interpretation of the
interval?
A....

20 women and 30 men between 18 to 60 years old and the
number of hours that they work. These information would be your
populations. For each group find the followings:
20 Women Ages = 19, 23, 40, 18, 60, 50, 21, 30, 33, 28,
33, 35, 28, 24, 28, 18, 19, 22, 25, 50
20 women work hours weekly = 40, 24, 30, 31, 19, 10, 21,
5, 40, 9, 8, 40, 37, 12, 20, 40, 20, 10, 40,...
