25. a) Probability that it is a student = 800 / 1000 = 0.80 or 80% b) Probability that it is a faculty member = 50 / 1000 = 0.05 or 5% c) Probability that it is an admin = 150 / 1000 = 0.15 or 15% d) Probability that it is a faculty or admin member = Probability that it is a faculty member + Probability that it is an admin member = 0.05 + 0.15= 0.20 or 20% e) Probability that it is anyone but an admin member = Probability that it is a student + Probability that it is a faculty member= 0.80 + 0.05 = 0.85 or 85%. f) To find the probability of each of these answers you would start by dividing the possible successful outcomes by the total number of possible outcomes. In the example E, the question asked for anyone except an administrator, therefore, taking the total amount of people minus the administrator will give you a category for those you want to have picked. After that, you would continue as if you had the successful possibilities divided by all possible
c) Use the lottery of part (b) and assume that the decision maker expresses indifference probabilities of
Examine two ways that companies can recruit qualified job applicants. Determine which method may be most effective and predict how it could benefit the company when hiring new employees.
Part 1. Using the sample data, perform the hypothesis test for each of the above situations in order to see if there is evidence to support your manager’s belief in each case a.-d. In each case use the Seven Elements of a Test of Hypothesis, in Section 6.2 of your text book with α =
b. Since we have a very well defined job description for each of the employees, measuring individual
Describe how you might go about determining scores for applicants’ responses to (a) interview questions, (b) letters of recommendation, and (c) questions about previous work experience.
A. Read the Chapter titled “Systems Administrator” (in my hard cover copy it starts on page 53, at the beginning of the “Goods and Services” section, but in your edition it may vary)
A firm offers routine physical examinations as part of a health service program for its employees. The exams showed that 8% of the employees needed corrective shoes, 15% needed major dental work and 3% needed both corrective shoes and major dental work. What is the probability that an employee selected at random will need either corrective shoes or major dental work?
Students in a science class have just received their grades on the first test. The instructor has provided information about the first test grades in some previous classes as well as the final average for the same students. Some of these grades have been sampled and are as follows:

a. Describe briefly the decision making issues that use statistics related to your chosen area of the Accounting profession. (5%)
1) Describe a decision-making process for employees with two different strengths. Determine how the process might be approached differently for each employee to produce the best results.
Observation 1- There are 2 paraprofessional and one administrator on duty. The 2 paraprofessionals and administrator should be
I would also make accommodations for the administrator by making sure this problem never occurs
4. Carefully consider the his reason for poor performance and decide on the facts and balances of probability as at to wether the employee is guilty or not
