1. Jeters Company uses a periodic inventory system and reports the following for the month of September.

Instructions

1. Compute the cost of ending inventory and the cost of goods sold using the FIFO, LIFO, and average-cost methods. (Round average unit cost to three decimal places)
2. Which costing method gives the highest ending inventory? The highest cost of goods sold? Why?
3. How do the average-cost values for ending inventory and cost of goods sold relate to ending inventory and cost of goods sold for FIFO and LIFO?
4. Calculate Inventory Turnover Ratio and Days in Inventory under FIFO, LIFO, and average-cost methods.
5. Calculate LIFO reserve (the difference between ending inventory using LIFO and ending inventory using FIFO) .

A financier whose specialty is investing in movie productions has observed that, in general, movies with "big-name" stars seem to generate more revenue than those movies whose stars are less well known. To examine his belief, he recorded the gross revenue and the payment (in $ millions) given to the two highest-paid performers in each movie for ten recently released movies

Movie Cost of Two highest paid performers    Gross Revenue

1    5.3 48

2 7.2    65

3 1.3    18

4 1.8 20

5 3.5 31

6 2.6 26

7 8.0 73   

8 2.4 23

9 4.5 39

10 6.7    58

a) Determine the standard error of estimate and describe what this statistic tells you about the regression line.

b) Determine the coefficient of determination and discuss what its value tells you about the two variables.

c) Calculate the Pearson correlation coefficient. What sign does it have? Why?

1.1 The work function of sodium is 2.75eV. Calculate the threshold wavelength of light at whigh emission of photoelectrons will first be observed.

1.1 Answer: Threshold wavelength = 451nm

1.2 The threshold wavelength for photoemission of electrons from potassium is 564nm. Calculate the maximum velocity of the photoelectrons that will be emitted when the metal is irradiated by light with a wavelength of 300nm.

1.2 Answer: Maximum velocity = 8.25*10^5 m/s

1.3 The ionization energes of electrons in the three highest occupied molecular orbitals of carbon monoxide are 14.0, 16.8 and 19.7eV. Calculate the kinetric energies in eV of the photoelectrons that will be emitted when CO is irradiated with (a) helium radiation of wavelength 58.4nm and (b) neon radiation of wavelength 74.2nm.

PLEASE explain the answer in detail

1.3 Answer: (a) Kinetic energies of photoelectrons are 7.2, 4.4, and 1.5 eV. (b) Photon energy of neon radiation = 16.7eV. This energy is sufficient to remove electrons only from the highest energy level of CO. These electrons will have a kinetic energy of 2.7eV.

Compression of a bit string x of length n involves creating a program shorter than n bits that returns

x. The Kolmogorov complexity of a string K(x) is the length of shortest program that returns x (i.e.

the length of a maximally compressed version of x).

(a) Explain why "the smallest positive integer not definable in under 100 characters" is paradoxical.

(b) Prove that for any length n, there must be at least one bit string that cannot be compressed to

fewer than n bits.

(c) Imagine you had the program K, which outputs the Kolmogorov complexity of string. Design

a program P that when given integer n outputs the bit string of length n with the highest

Kolmogorov complexity. If there are multiple strings with the highest complexity, output the

lexicographically first (i.e. the one that would come first in a dictionary).

(d) Suppose the program P you just wrote can be written in m bits. Show that P and by extension,

K, cannot exist, for a sufficiently large input n.

Consider two manufacturing companies of electrical devices with identical business fundamentals. Everything is the same for these two companies (same operations, same economic fundamentals, same suppliers, same customers and same managers). The only difference is in the way the two companies choose to report their
financials.
Company A follows a conservative financial reporting strategy by choosing accounting policies that report the lowest revenue and assets and the highest expense and liabilities.
Company B follows an aggressive financial reporting strategy by choosing accounting policies that report the highest revenue and assets and the lowest expense and liabilities.
Required:
(a) Explain how you can discover information that one company is being conservative in financial reporting and the other company is being aggressive in
financial reporting. You are required to give specific examples that are directly relevant to the context of these two companies being manufacturing companies of electrical devices.
(b) Explain how you could use this newly discovered information that a company is conservative or aggressive in reporting in active investing.

Problem 2: The Injury Severity Score (ISS) is a medical score to assess trauma severity and is calculated as follows. Each injury is assigned an Abbreviated Injury Scale (AIS) score in the range [0-5] which is allocated to one of six body regions (head, face, chest, abdomen, extremities, and external). Only the highest AIS score in each body region is used. The three most severely injured body regions (i.e. with the highest scores) have their AIS scores squared and added together to produce the ISS. Therefore, the value of the ISS is always between 0 and 75. Create a function called compute_iss that takes an array of 6 AIS values as its only input argument and produces the ISS value as its output. In your homework m-file, define the AIS array [3 0 4 5 3 0] and call to your function using this array as an argument. Find the ISS value for the defined AIS array. Make sure to add %comments.
