Having some trouble with this python question. An answer would be greatly appreciated!
#Write a function called are_anagrams. The function should
#have two parameters, a pair of strings. The function should
#return True if the strings are anagrams of one another,
#False if they are not.
#
#Two strings are considered anagrams if they have only the
#same letters, as well as the same count of each letter. For
#this problem, you should ignore spaces and capitalization.
#
#So, for us: "Elvis" and "Lives" would be considered
#anagrams. So would "Eleven plus two" and "Twelve plus one".
#
#Note that if one string can be made only out of the letters
#of another, but with duplicates, we do NOT consider them
#anagrams. For example, "Elvis" and "Live Viles" would not
#be anagrams.
#Write your function here!
#Below are some lines of code that will test your
function.
#You can change the value of the variable(s) to test your
#function with different inputs.
#
#If your function works correctly, this will originally
#print: True, False, True, False, each on their own line.
print(are_anagrams("Elvis", "Lives"))
print(are_anagrams("Elvis", "Live Viles"))
print(are_anagrams("Eleven plus two", "Twelve plus one"))
print(are_anagrams("Nine minus seven", "Five minus three"))

Major car manufacturers make use of computer simulations to
experiment with possible plant layouts. The simulations are
designed to reflect stochastic effects such as different demand
patterns, chance variations in processing times and breakdowns.
Hence the results of running a simulation to calculate shifts’
production rates need to be analysed using appropriate statistical
methods. Often these computer simulations are quite complex with
quite long runtimes, and hence there is an interest in using as few
runs of the simulation as possible, whilst still being able to
detect meaningful differences in performance between different
layouts.
The performance measure on which layouts are being compared is
hourly production rate. Suppose that two possible plant layouts are
being considered and that each been simulated for 12 shifts. The
observed production rates are tabulated below.
Plant Layout Production rates (cars per hour)
Layout 1 128 112 111 114 121 119 131 121 122 114 116 129
Layout 2 126 112 107 114 118 114 131 122 118 113 112 131
a) Suppose that the results from the two layouts are independent
samples. What conditions must be satisfied if we are to apply a
parametric (i.e. z or t) test to compare the production rates of
the two layouts?
b) Describe a way in which the observation rates from the two
layouts could be paired. What conditions must be satisfied if we
are to apply a parametric (i.e. z or t) test to compare the
production rates of the two layouts if the samples are
paired?
c) Supposing that the conditions you outlined in part (b) are
satisfied, conduct the appropriate parametric test to compare the
production rates of the two layouts. Clearly justify your choice of
test, state your null and alternative hypotheses and explain your
conclusion. Use a 5% significance level.
d) What is the approximate power of the test you have applied in
part (c) if the true difference in production rates is that Layout1
is on average 2.0 cars per hour faster than Layout2?

An automobile dealer conducted a test to determine if the time in minutes needed to complete a minor engine tune-up depends on whether a computerized engine analyzer or an electronic analyzer is used. Because tune-up time varies among compact, intermediate, and full-sized cars, the three types of cars were used as blocks in the experiment. The data obtained follow.

Festive Floral is gearing up for online carnation sales this Mother’s Day. They specialize in selling organic extra-large red and pink carnations. The price is $0.7 per stem, which includes free one-day shipping to the customer. Festive Floral pre-orders carnations directly from a certified organic farm at the cost of $0.15 per stem. The order is made prior to the growing season and flowers are grown accordingly, so the pre-order quantity cannot be changed. However, if Festive Floral runs out of pre-ordered carnations, they can always pick up more immediately from a local wholesaler that carries carnations of the same quality, at the price of $0.5 per stem. Historical demand for the past 10 years are given below.
Year: Red, Pink; 2008: 4008, 3288; 2009: 3948, 3648; 2010: 4092, 3636; 2011: 3984, 3684; 2012: 3996, 3792; 2013: 3888, 3720; 2014: 4128, 3564; 2015: 4104, 3744; 2016: 4380, 3828; 2017: 4392, 3744
For all questions below, please round your answers to two decimal points. Show your work by explaining the steps of your calculation.
(a) Using exponential smoothing with parameter ?? = 0.9, what is your forecast for red carnations in 2018? What is the MAD of your forecast?
(b) Based on the forecast above, what is the optimal number of red carnations to pre-order from the farm?
(c) Repeat Parts (a) and (b) for pink carnations.

a. Suppose Sora's revenue and free cash flow are expected to grow at a 5.4% rate beyond year four. If Sora's weighted average cost of capital is
9.0%, what is the value of Sora stock based on this information?
b. Sora's cost of goods sold was assumed to be 67% of sales. If its cost of goods sold is actually 70% of sales, how would the estimate of the stock's value change?
c. Return to the assumptions of part (a) and suppose Sora can maintain its cost of goods sold at 67% of sales. However, the firm reduces its selling, general, and administrative expenses from 20% of sales to 16% of sales. What stock price would you estimate now? (Assume no other expenses, except taxes, are affected.)
d. Sora's net working capital needs were estimated to be 18% of sales (their current level in year zero). If Sora can reduce this requirement to 12% of sales starting in year 1, but all other assumptions are as in (a), what stock price do you estimate for Sora? (Hint: This change will have the largest impact on Sora's free cash flow in year 1.)

Assume a firm has cash of $10 and a project that is either worth $130 or $80 (50% chance of each). The firm owes $110 to the bank. Similar to the example in class, the following shows the value of assets, debt, and equity where the amounts are calculated based on expected values.

Assume the firm is considering a new project which requires an initial investment of $5. If the new project is accepted, the $5 will be paid for using the firm’s cash. The new project has a $10 cash flow in the good state (i.e., increasing the “project” cash flows in the good state from $130 to $140). In the bad state, the new project’s cash flow is -$10 (i.e., decreasing the “project” cash flows in the bad state from $80 to $70). What is the expected value of the firm’s equity if the firm decides to accept this new project?
Refer back to the facts in the previous problem. What is the expected value of the firm’s debt if the firm decides to accept this new project?

IN C# WITH SCREENSHOTS OF THE CODE
RECURSION
Objectives
• Learn the basics of recursion.
Background
There are many problems that loops simplify, such as displaying
every pixel to a screen or
receiving repetitive input. However, some situations that can be
simplified with looping are not
easily solvable using loops. This includes problems that require
back tracking and being able to
use information from previous iterations, which would normally be
lost when using an iterative
loop. In those cases, it is much easier to use recursion to
logically solve the problem and it may
even reduce the amount of code that needs to be written.
Submission Guidelines:
You will turn in a Program code – 2 program files (one for each lab
problem)
Tasks
This lab has two parts:
1. Write a recursive method CalculateExponent( ) that takes in
two integer parameters, x
and y, and implements xy (x raised to the power y), where x and y
are integers and y > 0.
Write a driver program that calls this method from the Main
program.
2. Write a recursive method IntegerMultipy ( ) that takes in two
integer parameters i, j, and
implements i * j (integer multiplication), where i > 0. Define
the multiplication process in
terms of integer addition. For example, 4 * 7 is equal to 7 added
to itself 4 times. Write a
driver program that calls this method from the Main program.
Sample Output:
LAB 1:
Please enter a value for x

Please enter a value for y
