2. In one of the firms, the staffs are working in 4 different units. All of them using a statistical package to do their job. The CEO of the firm claims that there is a relationship between the statistical package and units of the firm. The units in the firm are Human Resources, Information Technologies, Accounting, and Finance. The packages used in the firm are EViews, Stata, SPSS Test this claim with 0.05 significance level by using the correct test and showing each calculation step in Ms Word file. You have to use the same steps which we used in the lecture. You can find the steps from lecture slides or recorded video. SEND IT IN MS WORD FORMAT NOT SCREENSHOT

a) Find the expected value for each cell by showing each step of the calculations. (10 points) If you don’t show each step, you will get 0

b) Find the Chi-Square calculated by showing each step of the calculations. (20 points) If you don’t show each step, you will get 0

c) Find the Chi-Square Table value (10 points)

d) Write your decision (10 points)

Calculate the photon energy and wavelength for the n = 4 to n = 2 transition and n = 4 to n = 3 transition for the hydrogen atom, H (Z = 1). Do not include uncertainty.

E ( 5--> 3) =

E ( 5 --> 2 ) =

λ ( 5--> 3 ) =

2. There are 4 financial statements available for the financial analysts to use in determining the value of a company’s stock. Discuss completely which financial statement you believe provides the most accurate indication of value for an investor? Which financial statement provides the least effective valuation information? Use examples from a company you have analyzed to underscore your point

2. A project will produce cash inflows of $3,200 a year for 4 years with a final cash inflow of $5,700 in year 5. The project's initial cost is $9,500. What is the net present value of this project if the required rate of return is 16 percent?

Please show all work preferably with the formulas, not just the grid. Thank you

4-2.What is the difference between a sunk cost and a differential cost?

A mixture of gases is at equilibrium:

4 NO (g) → 2 N2O (g) + O2 (g) ∆H = -199.5 kJ

(a) Does the equilibrium shift to the left or to the right when some O2 (g) is removed from the reaction mixture?

(b) Does the equilibrium shift to the left or to the right when some NO (g) is added to the reaction mixture?

c) In which direction does the equilibrium shift as the temperature is lowered?

(d) In which direction does the equilibrium shift as pressure is applied to the system?

give the structure corresponding to the name (s)-4-chloro-2-pentyne

A call that is $2 in-the-money trades for $4 today. A put written on the same stock that is $2 out-of-the-money trades for $2.25 today. Both options expire in 6 months and the risk free rate is 10% p.a. continuously compounded while the stock trades for $40. Are there any arbitrage opportunities available? If yes state the arbitrage strategy and prove

that it works.

- Part 2 – 4 Desk Checking Exercises – these are 3 programs (pseudocode) that are working and 1 program (Python). Explainthe intent of the pseudocode / program. If you use test data, note the test data.  .  You are NOT trying to find mistakes.

What does this do? Desk Checking #4:  Explain the intent of this code.  Be as specific as possible.  
List the data you use for example data.

import random

number = random.randint(1, 10)

keepGoing = input("Do you want to guess a number? Enter Y or N ")

while (keepGoing != "Y") and (keepGoing != "N"):

    keepGoing = input("Invalid Response." + " Please type Y or N. ")

while keepGoing == "Y":

    stringNumber = input("I'm thinking of a number. .\n Try to guess by entering a number between 1 and 10 ")

    userNumber = int(stringNumber)

    while (userNumber < 1) or (userNumber > 10):

        stringNumber = input("Number must be in the range of 1 to 10: Please try again: ")

        userNumber = int(stringNumber)

    if userNumber == number:

        keepGoing = "N"

        print("You are a genius. That's correct!")

    else:

        keepGoing = input("That's not correct. Do you want to guess again? Enter Y or N ")

        while (keepGoing != "Y") and (keepGoing != "N"):

            keepGoing = input("Invalid Response." + " Please type Y or N. ")
