The Human Resources manager of Slam’s Club was shocked by the revelations of gender discrimination by WalMart and wants to check whether there is a gender difference in average salaries in his firm. He takes a random sample of 145 male employees and 75 female employees. The average salary for the males is 54.372 thousands of USD, female average salary is 49.773 thousands of USD. He assumes that the variability of the salaries is equal and finds the pooled standard deviation of 10.844 thousands USD. What are the approximate values of the test statistics and critical value for the appropriate hypothesis test (significance level = 5%)? Answer is: test statistic = 2.982, and critical value = 1.971. I can get the test statistic. The part I need help on is how to get the critical value. please show the excel command used to obtain it in detail. |

The coronavirus pandemic is a human tragedy, affecting
hundreds of thousands of people globally. It is also
having a growing impact on the global value chain, hence the global
economy. All serious companies around
the world have therefore found innovative ways of keeping business
going nonetheless. One of such notable
companies is Ghana’s Kantanka Inc. The company has established a
dedicated team to ensure a simple but well-
managed set of processes that maximize the health and safety of
colleagues and customers. This team is led by
the CEO of the company. The focus of the team has been broken down
into five distinct work streams:
Employee management and wellbeing
Financial stress-testing and contingency planning
Supply chain monitoring
Marketing and sales
Any other business
Kantanka Inc. is a car manufacturing company originating from Ghana
which produces low-end vehicles. The
company’s competitive advantage stems from its unconventional but
effective and energy efficient technology
which is not found in most vehicles around the world. The dashboard
and other interior parts of the vehicles are
made from wood, and the vehicles are powered by car batteries and
solar energy.
Recently, they have added on aircrafts and mechanized farming
technologies. The company is set to take the
African market by storm. The company decided in 2015 to enter
Nigeria and Germany. With the backing of the
government of Ghana, negotiations with both countries succeeded as
negotiators from Nigeria and Germany
were in natural sync with the Ghanaian lobbyist contracted.
Once the company has gone international, it was only natural that
value chain activities of the company would
have to be rationalized to deal with the expansion, as well as all
forms of risk with respect to exchange rate
fluctuations. Speaking of financials, in this coronavirus pandemic
period, companies such as Kantanka Inc. that
entered into future contracts and used currency options as hedging
instruments would have less to worry about
since excuses from business partners would almost be
non-existent.
Recently in 2017, a company from Sậo Tome and Principé, called
PreZi contacted Kantanka Inc. to obtain
permission to use its technology. As to whether to agree or not to
the agreement is still under scrutiny by
Kantanka’s international expansion team.
a) Discuss five (5) ways the two negotiators can get along in order
for their cultural backgrounds not to
affect the outcome of their bargaining process.
b) Explain three (3) financial risks Kantanka Inc would definitely
encounter.
c) What five (5) benefits is Kantanka Inc likely to gain from
entering the German market?
d) Explain five (5) problems Kantanka Inc’s international expansion
team should anticipate before entering
the German market.
e) Explain the contractual strategy that would best characterize
the Kantanka-PreZi agreement once agreed
to.

Assume that the duration of human pregnancies can be described by a Normal model with mean 266266 days and standard deviation 1818 days. a) What percentage of pregnancies should last between 268268 and 276276 days? b) At least how many days should the longest 3030% of all pregnancies last? c) Suppose a certain obstetrician is currently providing prenatal care to 6868 pregnant women. Let y overbary represent the mean length of their pregnancies. According to the Central Limit Theorem, what's the distribution of this sample mean, y overbary? Specify the model, mean, and standard deviation. d) What's the probability that the mean duration of these patients' pregnancies will be less than 262262 days? a) The percentage of pregnancies that should last between 268268 and 276276 days is nothingm%. (Round to two decimal places as needed.)

If a human has 46 chromosomes and it undergoes meiosis this means it will produce haploid cells. (each cell having 23 chromosomes) However, if the cell replicates itself in interphase. Wouldn't we have 92 chromosomes once replicated? How would this translate in having a haploid # of chromosomes after meiosis I? If possible please draw a diagram I am super confused ;/

Please keep in mind that the discussion on fraud will evoke some emotions that is human. These are hypothetical situations.
On page 62 of the textbook, the Author Anderson and Enron case is discussed. This event demonstrates the breakdown of ethics and professional judgement in the 1990's / 2000 which resulted in accounting fraud. This occurred when accounting professionals failed to identify, report and correct unethical behavior because in doing so would harm the observer. Enron paid Anderson a total go $52 million making them the second largest client in there Houston Texas office.
The discovery of inaccurate financial statements and the failure to correct it and disclosure it in the 1997 earnings restatements were the primary reasons for fraud that has made Enron a household name today. This example demonstrates fraud from the top down where the professionals lost sight of there obligations during the audit.
The movie the Mule by Clint Eastwood proposed a similar dilemma in that ethics and professional judgement were ignored by all the individuals and fraud crimes were allowed to go uncorrected because there was no checks or voluntary disclosure which poses the question.
Question:
As a CPA or an accounting professional, how would you handle the issue of inaccurate earnings on financials statements if the lead auditor of your firm chose to allow it to go uncorrected.
How would you handle a $10 dollar variance versus a $10 million dollar variance?

(Note 1: To conduct your hypothesis test for parts (A) and (B) in problem #1, you need to use the randomized block design procedure in Excel denoted by “ANOVA: Two factors without Replication”).
(Note 2: For problem #2, you will be using “ANOVA: Two factor with Replication” procedure and will be conducting three hypothesis tests. Please make sure to specify your null and alternative hypotheses for each case and write your conclusion in each case).
