A Covid-19 diagnostic test made in China is 75% accurate on those persons who are infected and 80% accurate on those who are not. If 15% of the population of a particular city is infected and these tests are administered to almost everybody, compute the probability that a particular individual is infected, given that the test indicates that the individual has Covid-19. If the city has a million people, would you pay $38 million to test the whole population?

The Chartered Financial Analyst (CFA) designation is fast becoming a requirement for serious investment professionals. It is an attractive alternative to getting an MBA for students wanting a career in investment. A student of finance is curious to know if a CFA designation is a more lucrative option than an MBA. He collects data on 38 recent CFAs with a mean salary of $138,000 and a standard deviation of $34,000. A sample of 80 MBAs results in a mean salary of $130,000 with a standard deviation of $46,000.

1) Calculate the value of the test statistic. Do not assume that the population variances are equal. (Round all intermediate calculations to at least 4 decimal places and final answer to 3 decimal places.)

2) At the 5% significance level, is a CFA designation more lucrative than an MBA?

1. A sample of HR managers were selected to examine whether they expect job seekers of different races (Black vs. White) to negotiate salary offers. In the experiment, each participant was randomly assigned to view one of two versions of a fictitious job seeker’s resume. Resumes in the two conditions contained identical names, background, and job history information; the job seeker’s race was manipulated through the pictures shown at the top of the resume (Black male or White male). Each participant was asked to rate “Do you think this job seeker is to negotiate his salary offer?” (Responses were measured on a Yes-No format, 1 = Yes, 0 = No).

1. In the recent employee engagement survey, a sample of customer service employees were asked to report how often customers generally engaged in misbehaviors toward them in the past three months (measured on a 7-point Likert-type scale, 1 = never, 7 = always). The company wants to know whether different types of service employees (1 = full-time; 2 = part-time) received customer misbehaviors to the same extent.

1. A manufacturing company wants to explore whether there are regional differences in individual employee turnover intention. In a recent employee attitudinal survey, the company asked 120 employees at three different plants of the company (1 = Ohio, 2 = Michigan, 3 = Pennsylvania) about the extent to which they plan to leave the company in the next 6 months (measured on a 5-point Likert-type scale, 1 = very unlikely, 5 = very likely).

1. A university identified 50 faculty members who taught both online courses and traditional classroom courses in the Fall Semester 2018 and collected their Student Evaluation of Instruction (SEI) scores for the online courses and the traditional courses. The university wanted to use this dataset to evaluate whether instructors receive the same level of student evaluations when they teach online courses and traditional courses in classroom.

1. A research team wants to examine whether switching jobs can increase pay for both male and female faculty. They collected a sample of 200 assistant professors in Management who graduated in 2015 and asked them to report their salary (in dollar), their gender (1 = male, 2 = female) and whether they had changed jobs since graduation (1 = Yes, 0 = No).

Reliability vs. Validity -How would you explain the difference between reliability and validity? Which examples would you use to illustrate the concept?

NCSU: Fan Aptitude Test- Suppose this clip demonstrated a serious aptitude test. What would the results of a fan aptitude test reveal to us? Is this a valid test of intelligence? Why or why not?

NFL and the Wonderlic Test- Why do employers give job candidates tests like the Wonderlic? How do results on the Wonderlic apply to a bodily-kinesthetic career in the National Football League? What happened to Pat McAnally, the player who earned the only perfect Wonderlic score in NFL history? What does this say about aptitude tests like Wonderlic?

Debate has emerged and raged on regarding many African countries including Ghana not making rapid economic progress in an emerging knowledge economy. Poverty exists in spite of development being driven by technology, fuelled by information and powered by knowledge, and, many are oblivious to the reality that information and communication technology (ICT) cuts across all aspects of our lives.
We take a queue from the ICT driven economic experiences of the United States during the dot com boom and developments in Finland and other Western economies. We are informed by issues of globalization, the knowledge economy and the transformation of business processes using ICT in India, China, Korea and Malaysia. Close to us in Africa we are encouraged by economic growth using ICT in Rwanda and South Africa.
Pundits have argued that illiteracy is to be blamed, and mathematics and science education needs to be prioritized. Others say it is in our attitude fashioned by our past which does not relate development as an independent variable relative to other variables such as technology. While some view our challenges as lack of leadership to implement sustainable ICT policies and strategies at a macro and micro level, many argue that development of a nation’s economy has much to do with input from ICT personnel. They do not only belong to the domain of personnel with tacit knowledge of engineers who should provide infrastructure but such need to study policies that determine development

ii. What software option will you recommend to your ministry? Open source or Microsoft as proprietary software? Provide reasons for your recommendation.
iii. List FIVE (5) ways of how the TPS can be of use to a government department.
b.
i. What challenges are government organizations likely to face in deploying ICT to change their operations?

An Individual who makes $32,000 per year anticipate retiring in 30 years. If his salary is increased by $600 each year and he deposits 10% of his yearly salary into a fund that earns 7% interest, what is the future worth at retirement? Please don't copy from Chegg. Show work!

A prospective MBA student earns $55,000 per year in her current job and expects that amount to increase by 7% per year. She is considering leaving her job to attend business school for two years at a cost of $40,000 per year. She has been told that her starting salary after business school is likely to be $100,000 and that amount will increase by 10% per year. Consider a time horizon of 10 years, use a discount rate of 13%, and ignore all considerations not explicitly mentioned here. Assume all cash flows occur at the start of each year (i.e., immediate, one year from now, two years from now,..., nine years from now). Also assume that the choice can be implemented immediately so that for the MBA alternative the current year is the first year of business school. What is the net present value of the more attractive choice? Please round your answer to the nearest dollar.

A prospective MBA student earns $45,000 per year in her current job and expects that amount to increase by 6% per year.

She has been told that her starting salary after business school is likely to be $90,000 and that amount will increase by 16% per year. Consider a time horizon of 10 years, use a discount rate of 9%, and ignore all considerations not explicitly mentioned here.
