According to a 2004 report by Roger Boe et. Al. of Correctional Service Canada, the mean length of a Canadian jail sentence in 2001/2002 was ? = 4.10 months with σ = 9.75 months.
a) Can we assume that prison sentences are normally distributed? Please explain.
b) Using the central limit theorem, what is the approximate probability that the mean sentence for a random sample of 225 prisoners is more than 4.75 months?

The Sumatra-Andaman earthquake of December 26, 2004 with an undersea epicenter off the west coast of Sumatra, Indonesia, as reported in [1][2]. It triggered a series of devastating tsunamis that spread throughout the Indian Ocean killing approximately 230,000 people, including more than 168,000 in Indonesia and over 30,000 in Sri Lanka [2]. Sahana [2], a free and open source disaster management information system developed in Sri Lanka in the immediate aftermath of the Indian Ocean tsunami. Suppose that Sahana is addressing those recommendations and associated challenges from the Tsunami Evaluation Commission (TEC).

Williams-Santana, Inc., is a manufacturer of high-tech industrial parts that was started in 2004 by two talented engineers with little business training. In 2016, the company was acquired by one of its major customers. As part of an internal audit, the following facts were discovered. The audit occurred during 2016 before any adjusting entries or closing entries were prepared. The income tax rate is 40% for all years. |
| a |
A five-year casualty insurance policy was purchased at the beginning of 2014 for $34,000. The full amount was debited to insurance expense at the time. |
||||
| b. |
Effective January 1, 2016, the company changed the salvage value used in calculating depreciation for its office building. The building cost $592,000 on December 29, 2005, and has been depreciated on a straightline basis assuming a useful life of 40 years and a salvage value of $100,000. Declining real estate values in the area indicate that the salvage value will be no more than $25,000. |
||||
| c. |
On December 31, 2015, merchandise inventory was overstated by $24,000 due to a mistake in the physical inventory count using the periodic inventory system. |
||||
| d. |
The company changed inventory cost methods to FIFO from LIFO at the end of 2016 for both financial statement and income tax purposes. The change will cause a $950,000 increase in the beginning inventory at January 1, 2017. |
||||
| e. |
At the end of 2015, the company failed to accrue $15,300 of sales commissions earned by employees during 2015. The expense was recorded when the commissions were paid in early 2016. |
||||
| f. |
At the beginning of 2014, the company purchased a machine at a cost of $700,000. Its useful life was estimated to be ten years with no salvage value. The machine has been depreciated by the double-declining balance method. Its book value on December 31, 2015, was $448,000. On January 1, 2016, the company changed to the straight-line method. |
||||
| g. |
Warranty expense is determined each year as 1% of sales. Actual payment experience of recent years indicates that 0.75% is a better indication of the actual cost. Management effects the change in 2016. Credit sales for 2016 are $3,800,000; in 2015 they were $3,500,000.

The SAT and the ACT are the two major standardized tests that
colleges use to evaluate candidates. Most students take just one of
these tests. However, some students take both. The data below gives
the scores of 60 students who did this. How can we relate the two
tests?
(a) Plot the data with SAT on the x axis and ACT on the
y axis. Describe the overall pattern and any unusual
observations.
(b) Find the least-squares regression line and draw it on your
plot. Give the results of the significance test for the slope.
(Round your regression slope and intercept to three decimal places,
your test statistic to two decimal places, and your
P-value to four decimal places.)
| ACT = | + (SAT) |
| t = | |
| P = |
(c) What is the correlation between the two tests? (Round your
answer to three decimal places.)

The Travel Luggage Company “LugPro” designs and manufactures several different styles of soft- and hardcover luggage, briefcases, hanging bags, and purses. Their best-selling item is a line of hardcover luggage called the Trotter. It is produced in a basic five-stage assembly process that can accommodate several different outer coverings and colors. The assembly process includes constructing a heavy-duty plastic and metal frame; attaching the outer covering; joining the top and bottom and attaching the hinge mechanism; attaching the latches, lock, and handle; and doing the finishing work, including the luggage lining. Several hundred new pieces of luggage of particular shape and color are initiated through the assembly process each week in the company’s two factories. Travel Luggage Company also runs its own logistics operations to serve their customers in their 200 outlets all around Middle East.
