Albert, Bert, Clark, and David own equal interests



Albert, Bert, Clark, and David own equal interests in the capital and profits of an LLC that is taxed as a partnership. The LLC is a calendar-year taxpayer. For each of the following scenarios, determine (i) whether or not the LLC terminates and (ii) the tax consequences to the members:

a. Albert, Bert, and Clark simultaneously sell their entire interests in the LLC to David.
b. Albert, Bert, Clart and David simultaneously sell their entire interests in the LLC to Mr. Garrison, and unrelated third party.



c. On December 1, the LLC sells all its assets in exchange for a note of the purchaser. After December 1, the LLC merely holds the note and collects interest until March 31 of the following year, at which time the note is paid off and the LLC distributes the proceeds to the members in liquidation of the partnership.



d. Albert, Bert, and Clark form a new LLC. The new LLC purchases all of the assets of the old LLC, which liquidates by distributing the proceeds of the sale to the members.



e. Albert and Bert sell their entire interests to Clark and David, respectively, on the same day. Would your answer be different if Albert sells his interest six months after Bert sells his interest? One year and six months after Bert sells his interest?



f. Albert sells his interest to Bert, and, six months later, Bert sells Albert’s interest to Clark. Would your answer be different if Bert sells Albert’s interest to Mr. Garrison?



g. Albert and Bert each sell their entire interest in the LLC’s capital but only half of their respective interests in the partnership’s profits.



h. The partnership completely liquidates Albert’s and Bert’s interests on the same day.



i. Albert and Bert contribute their partnership interests to a corporation in exchange for stock of the corporation in a transaction governed by IRS 351.



j. Albert and Bert transfer their partnership interests on the same day to Mr. Garrison as a gift.



k. Albert and Bert each sell all but a de minimis amount of their LLC interests to Clark and David. A year and a day later, they sell the remaining portions to Clark and David.



l. The LLC converts to a general partnership.

Imagine you work for Quality Corporation



Imagine you work for Quality Corporation (Quality.ad) who has just recently bought Crescent Inc. (Crescent.ad) in a recent merger. Quality and Crescent have separate offices in St. Louis (Quality HQ), Little Rock, and Austin (Crescent HQ). Crescent also has offices in Oklahoma City, Tulsa, and Santa Fe. The desire is to establish trusts between the two (2) AD forests and consolidate core services (DNS, DHCP, etc.) as soon as possible. Both companies are running Server 2012 as Domain Controllers. Their primary DNS, DHCP, and Domain Controller servers are in the two (2) corporate headquarters with secondary servers located in the other cities to reduce latency.



For the Quality.ad domain, the Flexible Single Master Operation (FMSO) roles are located on Server01, which is located at the Quality HQ. For the Crescent.ad domain, the FSMO roles are located on RWDC01, which is located at the Crescent HQ. In addition, the Quality.ad domain has several servers configured as a Certificate Authority, and the Crescent.ad domain has a single Certificate Authority.



During this acquisition, you will need to consider the following:

•The Crescent Inc. has developed several enhancements for the widgets that your company produces. The engineering documents are installed on the ServerDocs located at the Austin office. You will need to configure the necessary systems so that the engineers from Quality Corporation can access these documents. Since these documents are considered proprietary and highly confidential, you must ensure that no other users except the two (2) engineering teams can access these documents and that the documents stay within the company..

•For both organizations, all user IDs and digital certificates from the other organization must be recognized. .



Write a six to eight (6-8) page paper in which you:

1.Explain the key considerations behind establishing trust relationships between the two (2) domains..

2.Suggest a method for consolidating Core Network services..

3.Provide a plan for integrating both AD forests eliminating duplication of service wherever possible..

Question 1: Smoking and Lung Cancer
Dr F. E. Tylecote, an English doctor, reported in 1927 that almost every lung cancer patient he had known about had been a smoker. And in 1936 two more doctors (Arkin and Wagner) reported that 90% of 135 men afflicted with lung cancer were chronic smokers. 

In these studies what do you think was the target population? 

What type of quantitative studies are these? Explain.
If we want to determine the level of the association between smoking and lung cancer, what other information is required? Hence state what type of quantitative study is required.

Question 2 
In the sport of archery in Question 2 of Assignment 1(please refer to another attached doc), scores are awarded depending upon the accuracy of the shot. Over a long period of time, a particular competitor has made scores according to the proportions in the table below.
Score   Proportion of times

50        0.25
25        0.30
10        0.10
  0        0.25

If the above proportions represent the probability that the competitor will achieve that score with a single shot, and the shots are considered to be independent, answer the following questions.

What are the expected (mean) score of the competitor with a single shot and the standard deviation of the competitor’s scores from assignment 1 (please refer to another attached doc)? 
Find a 95% probability interval for the total score of the competitor if they have a total of 150 shots.

Question 3 
Consider the “roll of the two cylinders” game in Question 3 of Assignment 1 (please refer to other attached doc) where two of five faced regular cylinders are rolled independently. Recall that the player’s score is the total on the two outcomes where the outcome of a roll is the number on the side in contact with the table. The casino charges players $6.50 to play the game (every roll of the two cylinders) and the return to the player is their score (in $).

A player starts the evening with $500 and play this game 36 times. Determine the following.

A 95% probability interval (to the nearest $) for the total amount of money the player will have returned to her after the 36 games.

A 95% probability interval for the amount of money that the player will take home with her.
What is the player’s chance of being ahead after playing this game 50 times?  
Calculate at least how many plays of the game are required such that the chance of the player being ahead is less than 1%.
Question 4 
“With whom do you find it easier to make friends?” 

A counsellor at a University claims that, when asked this question, 30% of students will say that they find it easier to make friends with the same sex, 20% with the opposite sex and the rest will claim that it makes no difference. 

The figures below show a sample collected by a keen Statistics student at the university. Use the Chi squared goodness of fit test (clearly state the relevant hypotheses are) to test the counselor’s claim. Use Microsoft Excel to determine the p-value for your test statistic as well as the 5% critical value for the test. Try to write down the Microsoft Excel commands.
