Lester Hollar is vice president for human resources for a large manufacturing company. In recent years, he has noticed an increase in absenteeism, which he thinks is related to the general health of the employees. Four years ago, in an attempt to improve the situation, he began a fitness program in which employees exercise during their lunch hour. To evaluate the program, he selected a random sample of eight participants and found the number of days each was absent in the six months before the exercise program began and in the last six months. Below are the results.

At the .05 significance level, can he conclude that the number of absences has declined? Estimate the p-value.

a. State the decision rule for 0.1 significance level: H₀ : μ_d≤ 0; H₁ : μ_d > 0. (Round the final answer to 3 decimal places.)

Reject H₀ if t > ???

b. Compute the value of the test statistic. (Round the final answer to 3 decimal places.)

Value of the test statistic ???   

c. Estimate the p-value? (Round the final answer to 4 decimal places.)

One of the week’s themes has been the human tendency to blindly follow rather than to resist injustice. Considering the world in the twenty-first century, what is a recent or current example of injustice and in what ways have we either failed to question, critique, challenge, and resist that injustice, or alternately, in what ways has active questioning, challenging, critiquing, and resisting rectified an injustice? Be specific and use as much detail as possible to explain your choice.

A Deloitte employment survey asked a sample of human resource executives how their company planned to change its workforce over the next 12 months. A categorical response variable showed three options: The company plans to hire and add to the number of employees, the company plans no change in the number of employees, or the company plans to lay off and reduce the number of employees. Another categorical variable indicated if the company was private or public. Sample data for 180 companies are contained in the Excel Online file below. Construct a spreadsheet to answer the following questions.

a. Conduct a test of independence to determine if the employment plan for the next 12 months is independent of the type of company. At a .05 level of significance, what is your conclusion?

Compute the value of the x^2 test statistic (to 2 decimals).

(___)

The p-value is (___) (to 4 decimals).

b. Discuss any differences in the employment plans for private and public companies over the next 12 months.

(___)% (to 2 decimals) of private companies plan on adding employees.

(___)% (to 2 decimals) of public companies plan on laying off employees.

Martin Seligman and Mihaly Csikszentmihalyi (2000) contend that if the study of human development turns towards a “positive psychology” then: …the social and behavioral sciences can play an enormously important role. They can articulate a vision of the good life that is empirically sound while being understandable and attractive. They can show what actions lead to well-being, to positive individuals, and to thriving communities. Psychology should be able to help document what kinds of families result in children who flourish, what work settings support the greatest satisfaction among workers, what policies result in the strongest civic engagement, and how people’s lives can be most worth living (44-45) One goal of positive psychology is to move beyond just describing our social reality to prescribing social policies that can transform society. Read Seligman and Csikszentmihalyi (Selction 8 of Classic Editions). What three ideas do they present in contrast to ‘psychology as pathology’? What are the implications of their ideas for social policy and/or your life?

A human resources manager keeps a record of how many years each employee at a large company has been working in their current role. The distribution of these years of experience are strongly skewed to the right with a mean of 333years and a standard deviation of 222 years. Suppose we were to take a random sample of 444employees and calculate the sample mean for their years of experience. We can assume independence between members in the sample.

What is the probability that the mean years of experience from the sample of 444 employees xˉxˉx, with, \bar, on top is greater than 3.53.53, point, 5 years?

1. a) In Chapter 9 (Week 9 Tutorial) we discussed the integration of the Human Resource Management and Payroll databases. In particular, we discussed different benefits of this integration in the Week 9 Tutorials.

   Some companies believe in the integration of HRM and Payroll systems. However, many firms do not agree with this integration. These companies maintain separate HRM information systems and Payroll.

   Required:

   Discuss both arguments. For this discussion, think in terms of (1) difference in employee background, and (2) functions performed by the HRM and payroll departments. [7 marks]

   [7 marks. Word limit: Up to 250 words.]

2. b) Mr Peter is the treasurer of a small charity and you asked him to explain the business activities and data processing operations involved in the payroll cycle of the charity.
