1. The waiting times​ (in minutes) of a random sample of 21 people at a bank have a sample standard deviation of 3.5 minutes. Construct a confidence interval for the population variance sigma squared and the population standard deviation sigma. Use a 99 % level of confidence. Assume the sample is from a normally distributed population. What is the confidence interval for the population variance sigma squared​?

2.You are given the sample mean and the population standard deviation. Use this information to construct the​ 90% and​ 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. If​ convenient, use technology to construct the confidence intervals. A random sample of 55 home theater systems has a mean price of ​$113.00. Assume the population standard deviation is ​$15.20.

a construction company that you work for asked you to perform an economic study to determine if it would be desirable to purchase a new road master scraper . you have assembled the following information . a new road master will cost $40000 and will have a service life of 20 years if a good maintenance plan is followed. maintenace operating cost wil amount to $12000 for year one and will increase $6000 each year that is in use .the market for used scrapers is shot and yu cannot plan to sell the road master for more than $0 whenever you decide to retire it ( if you do decide to purchase it ). use a value of 12% for marr and determine the number of years you should use for the economic life of the road master in your economic study

Question 1:- A potential investor collected attendance data over a period of 49 days at the North Mall and South Mall theaters in order to determine the difference between the average daily attendances. The North Mall Theater averaged 720 patrons per day with a variance of 100, while the South Mall Theater averaged 700 patrons per day with a variance of 96. Develop an interval estimate for the difference between the average daily attendances at the two theaters. Use a confidence coefficient of 0.95.

1) Due to the construction of a building, 150 kPa vertical stress increment takes place in a clay layer. The thickness of clay layer is 8m and there are a very thin sand layer above and a thick sand layer below it. If the final settlement is 0.08m, calculate the followings:

a) Required time in terms of month for 0.04m consolidation settlement

b) Amount of settlement in terms of meter, after 4 months of construction

c) During the construction, a machine is intended to be placed in to the building. However, the machine is sensitive to the settlement and amount of the settlement should not exceed 0.02m after placing this machine. Calculate the required time to satisfy the prerequisite in terms of months.

d) k value of the clay layer

mv = 1*10-4, cv = 0.4 m/month

Topic 1 (Note: Briefly in your own words 1 paragraph minimum, use and attach reference.)

Accounting Practices:

Using reading and research, locate a scholarly article that discusses accounting practices or the role of accounting in construction.

1.) Give a brief summary of what you learned and discuss how you will use this knowledge in your future career in construction management, what are the most common methods and programs used.

Discussion Topic 2 (Note: Briefly in your own words 1 paragraph minimum.)

2. Why do you think we need to depreciate some assets but not others?

Using the Issue, Rule, Analysis, Conclusion outline, I'm having trouble creating the IRAC for this situation....Happy City opened bidding for an airport construction project, by the usual process of advertising a request for bids. Crafty Construction submitted the lowest responsive bid. When the Happy City Council met to review the bid the Council members discovered the bid exceeded the budget for the project and discussed the possibility of negotiating a bid reduction. The city manager told the Council that Chris Crafty, owner of Crafty Construction, objected to further negotiations until Happy City formally awarded the contract to Crafty Construction, taking the position Happy City should award the contract in the amount of the original bid and afterward negotiate reductions in the scope of the work and/or contract price by submitting “work change orders” authorized by the contract. The City Council decided to award the contract to Crafty Construction “on the condition that the parties negotiate the work and price to bring it within the City’s budget;” adding that if Crafty would not participate in the negotiations, the City would rebid the project. Thereafter the City’s public works director suggested changes to Chris Crafty that would cut $100,000 from the project price to bring it within budget. Chris Crafty stated she felt she could do the reduction but was not prepared to discuss specifics. The next day Chris informed the public works director that she was confident that the price reduction of $100,000 could be accomplished based upon something like the suggested changes once a contract was signed. No further discussions occurred, and nothing was signed. Happy City eventually announced it would reject all bids, including Crafty Construction’s, as over-budget and rebid the project. Subsequently, Crafty Construction claimed it had a contract for the project, which Happy City breached by rebidding it. Happy City claims no contract ever existed. Who wins and why?

1. You are offered the opportunity to develop a 400,000 sf warehouse facility for General Foods in suburban Philadelphia. Attracted by your expertise as a local warehouse developer, General Foods has offered to sign a triple net lease for seven years at a rent for $2 million per year. They also insist that at the end of the lease term they have the option to purchase the property at $22 million. Their final major condition is that the project be completed and ready for occupancy in 11 months. If it is not complete by that time the deal is void.

You estimate that the property will cost $20 million to complete (including all costs) and that you should be able to complete it within ten months if you commence construction immediately. You believe that you can obtain a construction cost guarantee that should guarantee costs will not exceed $20.5 million. You believe that you will be able to obtain a $14 million to $15 million, seven-year, 25-year amortization loan, at a fixed interest rate of 8%, and a 50 basis point fee. You believe that you can close this loan in six to eight weeks from now.

You believe that your company can access approximately $8 million in equity, assuming that you can successfully tap into appreciated equity positions in three existing properties without triggering capital gains taxes on these positions. Your company will receive a development fee of roughly 3% of project costs (this cost is included in your $20 million cost estimate).

Finally, vacancy rates in the market are approximately 4%, gross rents in the market run $7-9 psf, with operating expenses and taxes running $2-$4 psf. Negotiations are over and it is time to make a decision.

Should you agree to develop the property? Give your reasons.
