Almost all companies utilize some type of? year-end performance review for their employees. Human Resources? (HR) at a? university's Health Science Center provides guidelines for supervisors rating their subordinates. For? example, raters are advised to examine their ratings for a tendency to be either too lenient or too harsh. According to? HR, "if you have this? tendency, consider using a normal distribution —?10% of employees? (rated) exemplary,? 20% distinguished,? 40% competent,? 20% marginal, and? 10% unacceptable." Suppose you are rating an? employee's performance on a scale of 1? (lowest) to 100? (highest). Also, assume the ratings follow a normal distribution with a mean of 49 and a standard deviation of 15.

Personnel tests are designed to test a job? applicant's cognitive? and/or physical abilities. A particular dexterity test is administered nationwide by a private testing service. It is known that for all tests administered last?year, the distribution of scores was approximately normal with mean 78 and standard deviation 8.4.

a. A particular employer requires job candidates to score at least 82 on the dexterity test. Approximately what percentage of the test scores during the past year exceeded 82??

b. The testing service reported to a particular employer that one of its job? candidate's scores fell at the 90th percentile of the distribution? (i.e., approximately 90?% of the scores were lower than the? candidate's, and only 10?% were? higher). What was the? candidate's score?

Human Development Data Set: Questions are posted in next post.

You are provided with data for several nations from the Human Development Report, 2017.

1. Compute summary statistics (mean, median, mode, standard deviation etc.) for the variables of GDP (GDP per capita in thousands of dollars) and Internet use.

Provide descriptions of the distributions based on the summary statistics. Address skewness in your description.

2. Generate a scatterplot with clearly labeled axes CO2 and GDP. CO2 will be on the Y axis. Comment on what you see.
3. Compute the correlation between CO2 and GDP and interpret it. Refer to both the strength and direction of the correlation in your interpretation.
4. Using the variable Internet Use, construct the 1^st, 2^nd, and 3^rd standard deviation from the mean intervals and calculate the percentages for each. Then make a short interpretation on whether they match the percentages in the Empirical Rule.

Hypothetical Human population matrix over a period of time of 20 year intervals.

Age 0-20 20-40 40-60 60-80   

0-20 [ .24 .98 0 0]

20-40 [ .77 0 .92 0]

40-60 [ .04 0 0 .57]

60-80 [ 0 0 0   0]

Complete the calculation to determine what the population distribution will be 200 years after the initial probability distribution shown in the example as P= [1000, 1000, 1000, 1000]. The formula is P*T^10 (there are 10 sets of 20 in 200)

After 200 years, # of people in the 0-20 range = _______________?

After 200 years, # of people in the 20-40 range = _______________?

After 200 years, # of people in the 40-60 range = _______________?

After 200 years, # of people in the 60-80 range = _______________?

Now, using the same population dynamics matrix, determine what the probability distribution will be after 320 yrars if the initial probability distribution is P= [1100, 1700, 1100, 1000] ? The formula is P*T^16 (there are 16 sets of 20 in 320)

After 320 years, # of people in the 0-20 range = _______________?

After 320 years, # of people in the 20-40 range = _______________?

After 320 years, # of people in the 40-60 range = _______________?

After 320 years, # of people in the 60-80 range = _______________?

Business had been slow since the beginning of the year, and each of the operating plants had laid off workers. Ken’s dismissal was processed through the Human Resources Department, but the information was not relayed to the corporate payroll office. As had been the policy, checks for workers at remote sites were mailed to the employees. The mailing of Ken’s checks continued for the next four weekly paydays. It wasn’t until the monthly payroll reports were sent to Ken’s supervisor that the error was detected.

1. Ken refused to return the four extra checks?

2. What actions should the company take?

3. Is Ken being ethical?

Silicone implant augmentation rhinoplasty is used to correct congenital nose deformities. The success of the procedure depends on various biomechanical properties of the human nasal periosteum and fascia. A sample of 30 (newly deceased) adult rhinoplasty patients had a mean failure strain (%) of 28.2 and a standard deviation of 4.1.

a Calculate a 90% confidence interval for the true mean failure strain for all rhinoplasty patients.

b Based on your confidence interval in part a, is it plausible that the true mean failure strain is 30%?

c Conduct a hypothesis test at the 0.01 level to determine if the true mean failure strength is 30%.

d Does your conclusion in part c match your answer in part b? Should it?

Telehealth is becoming very popular in many areas, giving patients access to quality care when they need it. Previously, telehealth was reserved for remote areas, but we are seeing a shift in care so that these health services are available to many people that need them. However, this system presents several challenges. Suppose that a patient, provider and telehealth proxy are all in different states. If there is a malpractice claim, which state should it be filed in? What about licensure of these professionals – should providers be licensed in additional states where they provide telehealth services? Include how you believe this additional human computer interaction could or could not change the face of health care. Are there any usability factors to be considered in implementation of telehealth systems?
