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.

Assignment: (Save this file as A71.cpp) Write a program to calculate the gross pay for an assembly line employee that works for a company that pays all assembly line workers $7.50 hour. Any employee that works over 40 hours per week is compensated by being paid timeandonehalf for each hour over 40. a. Use main( ) as the driver function. Allow the user to compute as many employees as desired. b. Write the function getName( ) that prompts for the name of the employee and returns it to main( ). c. Write the function getTime( ) that prompts the user for the time worked for that week and returns this value back to main( ). Do not allow the user to enter a negative value for the hours. Display an error message and keep prompting until a valid value is entered. d. Write the function computePay( ) that calculates the gross pay of the employee using the time entered by the user and returns the calculated gross pay back to main( ). e. Write the function displayPay( ) that takes as input the employee’s name, the gross pay and time worked from main( ) and displays these values.

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 K111 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  $

b. Determine the direct materials quantity variance for batch K111. 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.

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%.
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

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.

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 4year 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 eighthigh 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!

b. With the use of a diagram, distinguish between change in demand and change in quantity demanded. c. Trade unions always try and get a much higher wage rate than what the market is willing to pay. Using and appropriate explain what will likely happen in the labour market if the wage rate demanded by a trade union is above the market equilibrium wage.
d. Calculate the following different elasticities:
i. A price increase from P2 to P10 causes quantity demanded to change from 80 units to 30 units. Calculate and interpret price elasticity of demand.
ii. Income increase by 10% results in quantity demanded increases by 5%. Calculate and interpret income elasticity of demand.
iii. Quantity of good B increases by 50% because of an increase in price of good A by 40%. Calculate and interpret cross elasticity of demand.
iv. How would a firm manipulate the prices of goods in diiii in order to maximize revenue and profits?
