A steel company is considering the relocation of one of its manufacturing plants. The company’s executives have selected four areas that they believe are suitable locations. However, they want to determine if the average wages are significantly different in any of the locations, since this could have a major impact on the cost of production. A survey of hourly wages of similar workers in each of the four areas I performed with the following results.

a. You should not be surprised by the presence of a large number of outliers because the magazines are highly heterogeneous and it is unrealistic to expect a single relationship to connect all of them. Find outliers and high leverage points. Delete the outliers and obtain an acceptable regression equation that relates advertising revenue to advertising pages.

b. For the deleted data, check the homogeneity of the variance. Choose an appropriate transformation of the data and fit the model to the transformed data. Evaluate the fit.

Standard Product Cost, Direct Materials Variance

Condiments Company uses standards to control its materials costs. Assume that a batch of ketchup (2,700 pounds) has the following standards:

Standard Quantity Standard Price
Whole tomatoes 4,500 lbs. $ 0.53 per lb.
Vinegar 250 gal. $ 3.20 per gal.
Corn syrup 22 gal. $ 11.80 per gal.
Salt 100 lbs. $ 2.90 per lb.

The actual materials in a batch may vary from the standard due to tomato characteristics. Assume that the actual quantities of materials for batch K-111 were as follows:

4,700 lbs. of tomatoes
240 gal. of vinegar
23 gal. of corn syrup
99 lbs. of salt

a. Determine the standard unit materials cost per pound for a standard batch. If required, round amounts to the nearest cent.

Ingredient Standard Cost per Batch
Whole tomatoes $
Vinegar $
Corn syrup $
Salt $
Total $
Standard unit materials cost per pound $

b.  Determine the direct materials quantity variance for batch K-111. If required, round amounts to the nearest cent. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number.

Ingredient Materials Quantity Variance Favorable/Unfavorable

An electric utility is considering a new power plant in northern Arizona. Power from the plant...

An electric utility is considering a new power plant in northern Arizona. Power from the plant would be sold in the Phoenix area, where it is badly needed. Because the firm has received a permit, the plant would be legal; but it would cause some air pollution. The company could spend an additional $40 million at Year 0 to mitigate the environmental problem, but it would not be required to do so. The plant without mitigation would cost $240.41 million, and the expected cash inflows would be $80 million per year for 5 years. If the firm does invest in mitigation, the annual inflows would be $84.88 million. Unemployment in the area where the plant would be built is high, and the plant would provide about 350 good jobs. The risk adjusted WACC is 16%.

  1. Calculate the NPV and IRR with mitigation. Round your answers to two decimal places. Enter your answer for NPV in millions. Do not round your intermediate calculations. For example, an answer of $10,550,000 should be entered as 10.55. Negative value should be indicated by a minus sign.
    NPV $   million
    IRR  %

    Calculate the NPV and IRR without mitigation. Round your answers to two decimal places. Enter your answer for NPV in millions. Do not round your intermediate calculations. For example, an answer of $10,550,000 should be entered as 10.55.
    NPV $   million
    IRR  %

  2. How should the environmental effects be dealt with when evaluating this project?
    1. The environmental effects should be ignored since the plant is legal without mitigation.
    2. The environmental effects should be treated as a sunk cost and therefore ignored.
    3. If the utility mitigates for the environmental effects, the project is not acceptable. However, before the company chooses to do the project without mitigation, it needs to make sure that any costs of "ill will" for not mitigating for the environmental effects have been considered in the original analysis.
    4. The environmental effects should be treated as a remote possibility and should only be considered at the time in which they actually occur.
    5. The environmental effects if not mitigated would result in additional cash flows. Therefore, since the plant is legal without mitigation, there are no benefits to performing a "no mitigation" analysis.
  3. Should this project be undertaken?
    1. The project should be undertaken only under the "mitigation" assumption.
    2. The project should be undertaken since the IRR is positive under both the "mitigation" and "no mitigation" assumptions.
    3. The project should be undertaken since the NPV is positive under both the "mitigation" and "no mitigation" assumptions.
    4. Even when no mitigation is considered the project has a negative NPV, so it should not be undertaken.
    5. The project should be undertaken only if they do not mitigate for the environmental effects. However, they want to make sure that they've done the analysis properly due to any "ill will" and additional "costs" that might result from undertaking the project without concern for the environmental impacts.

In python,

Part 1: Estimate the value of e.

e is defined as  as n goes to infinity. So the larger the value of n, the closer you should get to e.

math.e is defined as 2.718281828459045

You'll write a program that uses a while loop to estimate e to within some defined error range, while having a limit on how many iterations it will attempt.

Part 2: Palindrome detection

A palindrome is a string that is the same forwards and backwards.

Madam I'm Adam
Racecar
Was it a cat I saw?

There are many sophisticated ways of detecting palindromes. Some are surprisingly simple (s == s[::-1])

You will use a for loop to iterate over the contents of the string to determine if it is a palindrome.

Beware! There are many solutions online. Don't fall prey to looking this one up. It's not as hard as it looks. Draw it out on paper first and think through how you index the string from both ends.

skeleton of code:

#
# Estimate the value of e.
#
# Write a routine that uses a while loop to estimate e.
#
# Arguments:
#       delta: How close the estimate has to come
#       n:      Maximum number of attempts
#
# Algorithm:
#       Compare math.e to your value of e and if the difference is
#       greater than delta, increment count and make a new estimate. A
#       Assuming the count variable is "i", the formula for e is:
#           e = (1 + 1/i)**i
#
#       Stop when the difference between math.e and your value is less
#       than delta or the count variable reaches n.
#
# Output:
#       Return a tuple of the delta and the number of tries you made
#
import math
def estimateE(delta, n):
    pass

#
# Return true if s is a palindrome
#
# Look at the indices of a string s = "abcdcba":
#   0, 1, 2, 3, 4, 5, 6
# -7, -6, -5, -4, -3, -2, -1
#
# To be a palindrome, s[0] == s[-1], s[1] == s[-2], etc
#
# Return True if s is a palindrome
#
# Use ONLY a for loop, len, and slicing.

def palindrome(s):
    pass

A project has an initial requirement of $190,151 for new equipment and $11,289 for net working capital. The installation costs are expected to be $15,824. The fixed assets will be depreciated to a zero book value over the 4-year life of the project and have an estimated salvage value of $77,787. All of the net working capital will be recouped at the end of the project. The annual operating cash flow is $78,979 and the cost of capital is 14% What is the project's NPV if the tax rate is 28%?

Write a C++ program that inputs three integers in the range [1..13] that represent a hand of three cards. Your program should output an English evaluation of the hand.

In the output, cards will be described as follows:

- 2–10 are described by the words for their numeric values: two, three, etc.

- 1 is called an ace, 11 is called a jack, 12 is called a queen, and 13 is called a king.

The evaluation of a hand is based on the first of the following cases that matches the cards:

- All three cards are equal to each other.

Sample output for 4 4 4: You have three fours.

- The three cards form a straight (three successive values).

Sample output for 6 8 7: You have an eight-high straight.

- Two cards (a pair) are equal.

Sample output for 6 3 6: You have a pair of sixes.

- Whatever is the highest card.

Sample output for 11 1 8: You have a jack.

Recommend sorting the card values before trying to evaluate the hand –that makes it much easier. Also, work on one thing at a time: first determine what kind of hand (3 of kind, 2 of kind, straight,...) and then determine what is the “significant” card for that hand (it becomes very messy and exhausting if you try to do both at the same time!). Check for card values being equal to each other (card1 == card2), not specific values (card1 == 1 && card2 == 1 || card1 == 2 && card 2 == 2 || ...). If you check each value, your program will be hundreds of lines long!
