I know…I know, but we need to practice statistical formulas so that we understand the process. Below are 8 statistics questions worth 5 points each. Please complete in a Word document or Excel and show your calculation process. A. Twelve (12) students completed COUN 6083 Research and Program Evaluation with the following grades: 98 96 98 91 87 88 87 93 76 87 86 87 What is the mean of the data set above? (5 pts) What is the frequency or mode of the data set above? (5 pts) What is the median of the data set above? (5 pts) What is the variance and standard deviation of the data set above? (5 pts) B. Nine (9) high school students with high levels of depression were asked the number of hours per day spent on social media. The numbers are as follows: 5, 7, 4, 6, 5, 2, 6, 3, 5 What is the mean of the data set above? (5 pts) What is the frequency or mode of the data set above? (5 pts) What is the median of the data set above? (5 pts) What is the variance and standard deviation of the data set above? (5 pts)

There are many factors to consider when comparing job offers – the salary and benefits, the taxes, the
cost of living, the cost of leaving, and other costs incurred by taking the new job. Here are three job
offers for similar types of work for which you are eminently qualified. You currently hold the job in
Silicon Valley, but you are considering choosing the offers elsewhere.
Location Silicon Valley, CA Seattle, WA Austin, TX
Salary Offer $250K $200K $150K
Retirement Benefits 8% contributed by
employer
6% contributed by
employer
7% contributed by
employer
Other Benefits Stock option worth
$200K
Tax Rate 13% 12% 7%
Cost of Living 60% above national
average
40% above national
average
20% above national
average
Cost of Leaving Not vested yet. You
lose 4 years of
retirement accrued
To break the contract
will cost $50,000
penalty.
Not vested yet. You
lose the stock option.
Relocation Costs Up to $10,000
reimbursed
Up to 4% of salary Compensated an
amount of $3000
You currently spend around $6000 per month in living expenses; you would live a similar lifestyle
wherever you work. Project your total earning for five years into the future whether you stay put or
take one of the other job offers. Which scenario provides the greatest accumulated earnings after five
years?

Introduction
The virus that causes COVID-19 (coronavirus disease 2019) is just one member of the coronavirus family of viruses, and not the first to have caused a pandemic. In 2003, another coronavirus caused a pandemic of a disease called SARS (severe acute respiratory syndrome) that resulted in about 770 deaths in 29 countries (none in the United States). This was far fewer than the global deaths from COVID-19, which were in the millions.
Discussion Question
Use your critical thinking skills to answer the following questions, which compare the two pandemics.
Most people infected with the SARS virus showed symptoms of the disease soon after they were infected. In contrast, up to half of those infected with the COVID-19 virus never showed symptoms. Explain why this difference made the COVID-19 pandemic harder to track and control than the SARS pandemic.
Consider these two measures of a disease: (1) the incubation period, which is the time between when a person shows symptoms, and (2) the latent period, which is the time between when a person becomes infected and when that person becomes infectious. For SARS, the latent period is longer than the incubation period, but the reverse (incubation period is longer than the latent period) was true for the original form of COVID-19. Explain why this difference made the COVID-19 pandemic harder to track and control than the SARS pandemic.
Consider two more measures of a disease: (1) the fatality rate, which is the percentage of people who die after being infected with a particular disease, and (2) the initial reproduction number (R), which is the average number of people that one infected person will infect. The SARS and COVID-19 viruses both had roughly the same initial R value, meaning that both diseases are about equally contagious in the absence of any population immunity or steps taken to slow the disease spread. However, SARS had a much higher fatality rate, killing an estimated 11% of infected people (and doing so fairly quickly), compared to less than 1% for COVID-19. Is it possible that because SARS was deadlier it was less likely to cause a large pandemic? Explain.
