Preliminary plans are under way for the construction of a new stadium for a major league baseball team. City officials have questioned the number and profitability of the luxury corporate boxes planned for the upper deck of the stadium. Corporations and selected individuals may buy the boxes for $320,000 each. The fixed construction cost for the upper deck area is estimated to be $5,760,000, with a variable cost of $160,000 for each box constructed. (a) What is the break-even point for the number of luxury boxes in the new stadium? X = (b) Preliminary drawings for the stadium show that space is available for the construction of up to 48 luxury boxes. Promoters indicate that buyers are available and that all 48 could be sold if constructed. (1) What is your recommendation concerning the construction of luxury boxes? O Build the luxury boxes. O Do not build the luxury boxes. (ii) What profit is anticipated (in dollars)? (Enter a negative value if a predicted loss.) $

Integrated Health was a large private, nonprofit health care system located in Tempe,Arizona. A year ago, the decision was made to implement a computerized medication administration record (MAR) at Integrated Health. During the first year, the MAR system would be implemented at Central Hospital of Tempe. After the “bugs” were worked out, the computerized MAR would be implemented system-wide. The MIS department at Central Hospital was designated as the initiator and direction setter for the project. Art Smith, the Chief Information Officer at Central Hospital assigned Kate Cohen, a programmer/analyst, as project leader. Kate had the responsibility for developing and implementing the MAR project at Central. Kate did the programming work for the MAR and assembled a team from Pharmacy Services, Nursing Services, and Internal Auditing. Members of the project team provided feedback on the software, made suggestions related to user training, and worked on an implementation schedule. Both team…

Given the information below, what are the estimated expected (mean) times (in weeks) for activities A-H?  What are the estimated standard deviations (in weeks) in the times for activities A-H?

Consider the office renovation project data in the following table. A​ "zero" time estimate means that the activity could take a very small amount of time and should be treated as a numeric zero in the analysis. a. Based on the critical​ path, find the probability of completing the office renovation project by 39 days. Refer to the standard normal table ​(Make sure to round all intermediate calculations for te and variance to two decimal​ places.)   The probability is

11-23 Tom Schriber, the director of personnel of Management Resources, Inc., is in the process of designing a program that its customers can use in the job-finding process. Some of the activities include preparing resumés, writing letters, making appointments to see prospective employers, and researching companies and industries.
