The Human Resources Department of a company conducts a survey to determine if a new medical insurance plan is viewed favorably. Out of 200 employees surveyed 80 said they liked the change.   

a. Calculate a 95% confidence interval for the population proportion who view the change favorably.

b. What is the proper interpretation of the interval constructed in Part a?

i. There is a 95% chance that the population proportion lies within the constructed interval.

ii. If 20 similar confidence intervals were constructed on average 19 of these would contain the population proportion.

iii. The interval defines the values that are not plausible for the population proprtion.

Laura and Andrea work as independent consultants in the area of human resources for companies that need training for their collaborators. The two give leadership conferences and do customer service training. It is estimated that the frequency with which they provide one or the other service can be framed within a Poisson process with different frequency rates: Laura gives leadership conferences with an average rate of 4 per month, while customer service trainings are performed at an average frequency of 9 every two months. On the other hand, it is estimated that in a month Andrea dictates, on average, 3 leadership conferences, while she is able to teach 72 customer service training courses per year, on average.
If necessary, assume a month is 4 weeks or 30 days. According to the previous information, answer:

a. What is the probability that in 18 weeks, Laura will teach 12 customer service courses and Andrea will give 10 leadership conferences?

The human resources department of a major corporation announced that the number of people interviewed by the corporation in one month has a mean of 108 and a standard deviation, σ, of 15. The management of the corporation suspects that the standard deviation differs from 15. A random sample of 17 months had a mean of 113 interviews, with a standard deviation of 9. If we assume that the number of people interviewed by the corporation in one month follows an approximately normal distribution, is there enough evidence to conclude, at the 0.01 level of significance, that the management's claim is correct?

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.)

For this assignment, you are an HR manager for ABC corp. The director of sales would like you to give a presentation to her team of seven sales managers about the importance of creating a legally defensible job description.

2. Discuss why the examples identified are unlawful.
3. Discuss the ramifications of listing unlawful job requirement criteria on job descriptions.
4. Then give three examples of criteria that are legally satisfiable instead.

It has long been known in the field of human genetics that wavy hair is the expression of a heterozygous genotype in which the allele for straight hair is paired with the allele for curly hair. Camille married Devin, and they both have wavy hair.What is the probability that their first child will have: a. wavy hair? b. curly hair? c. straight hair?

What is the name of the genetic phenomenon described in question above?

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 ;/
