Smart-guru is already work in this assignment.. thanks for others.

Critique key points about the scenario using a t-test, suggest an improvement to it, and explain your reasoning.

Scenario, I want to test a male enhancement drug.  I have 20 Men of different races ranging from ages 35-65.  I have the men rate their sex drive before and after taking the drug. Does the drug do anything?  In my scenario what would need to change to result in the need for a two-sample t test would be the number of groups.  To have a two sample t test you have to compare two sample typesgroups.  The two sample scenario would be categorized as independent because they are not related and do not overlap in any way.  When it comes to Independent random sampling “The observations within each group have been randomly sampled independently of each other, and all of the observations in one group are independent of all of the observations in the other group.  The dependent variable of this study would be the scores from the men, because the scores will change. The independent variable of the study would be the men. 

You have just attended a manager’s meeting about establishing self-directed, high-performing teams. The company is concerned because some of the managers are having success building self-directed, high-performing teams while others are not. A discussion occurred that identified the characteristics of the successful team building elements and compared them to those managers that have not been successful. This is a situation where those who are struggling need to learn from those who are doing well. The discussions included identifying what could be going wrong and what steps might be taken for success.

You have been asked to write a research report that summarizes the meeting and offers some recommendations that might be helpful to those managers who are struggling. Specifically, your report must include:

• Identification of the difficulties the managers may be having in establishing self-directed, high-performing teams
• Identification of the successful characteristic of establishing self-directed, high-performing teams
• Recommendations for success
• A designed plan that might help guide the struggling managers and improve negotiation and conflict resolution skills

Use the Library and Internet to research this topic.

Present your findings as a 3-4 pages Word document formatted in APA style.

3-4 body pages

TITLE PAGE. Remember the Running head: AND TITLE IN ALL CAPITALS

• ABSTRACT. A summary of your paper…not an introduction. Begin writing in third person voice.
• BODY. The body of your paper begins on the page following the title page and abstract page and must be double-spaced (be careful not to triple- or quadruple-space between paragraphs). The type face should be 12-pt. Times Roman or 12-pt. Courier in regular black type. Do not use color, bold type, or italics except as required for APA level headings and references. The deliverable length of the body of your paper for this assignment is 3-4 pages. In-body academic citations to support your decisions and analysis are required. A variety of academic sources is encouraged.
• REFERENCE PAGE. References that align with your in-body academic sources are listed on the final page of your paper. The references must be in APA format using appropriate spacing, hang indention, italics, and upper and lower case usage as appropriate for the type of resource used. Remember, the Reference Page is not a bibliography but a further listing of the abbreviated in-body citations used in the paper. Every referenced item must have a corresponding in-body citation.

This is the hardest homework so far, by a substantial margin. Think of it as a practice Facebook or Google internship interview coding problem! 

The most elegant solution among the first few submitted will get a special prize, and an invitation to work in our lab. TBA. Focus on elegance & simplicity, for now, rather than efficiency. 

First part is simpler, involving addition of arbitrary long numbers, & multiplication with single-digit multipliers. 

The second part will simply adding a few lines (I expect 10-15) to the first part, to produce multiplication of arbitrary-long
numbers. 

PART1: longpart1.c

The parts of this assignment are: 

0) Checking if a long positive decimal number is valid (i.e., has no non-numerical, non-decimal digits)
1) Addition of two long positive numbers. 
2) Multiplication of the first long positive number by  numbers between 2 and 9

You’ll do this by implementing one non-recursive main function, to do each of the operations. This main function will set up initial conditions and call a recursive helper function to actually do the operation in a recursive manner. 

All above have to be implemented using a recursive helper function for each of the above. ALL HELPER FUNCTIONS HAVE to be recursive.  There should be one recursive helper function for the checking, one for the addition, and one for the single digit mutiplication. If it isn’t, we will consider it cheating, and award negative points that will be carried into your total score. See below. 

You will store them as char * strings, and implement these subroutines that call the recursive helper functions:

int digcheck(char *theno) is “theno” a string that is a valid decimal number? 
char *add2(char *n1, char *n2)  add 2 numbers n1 and n2 and return the result 
char *smult(char *n1, char d) multiply long number n1 by a single digit number d and return the result.

The add2 and smult are non-recursive functions will allocate memory for the result, on the heap,  (to be discussed), and perhaps do some copying and then call helper functions which MUST BE recursive. Hint: These helper functions will require an extra argument, the carry digit. Think about it. They both return a pointer to the result, which is a string that they allocate on the heap. The helper recursive function will be essentially marching along from lower significant digits to upper significant digits. Think recursively: can you add single decimal digits stored in character form? OK. Now, then. If you have
successfully added the succeeding two streams of digits, and have a carry digit, how do produce the next digit, and move on? 

The design of these helper functions is up to you, but they MUST BE RECURSIVE. Please ask for help if you don’t know how; don’t submit a non-recursive solution, because you WILL get negative points for that. We will spot check a number of homeworks by hand, if the solutions are not recursive, you WILL get -10 points for homework, which will be deducted from your over all  homework score. If you don’t know how to do it recursively, ask us for help. Don’t submit a non-recursive solution. Next week’s tutorials will be talking about this homework, and I will have extra office hours next week. We want you to succeed! 

PART2 (longpart2.c)   Multiplication of two long positive numbers; also implemented recursively. My implementation of the long multiplication is a seven-line recursive routine, that calls add2, and another little helper function. The signature of the recursive routine is: 

char *longmult(char *num1, char  *num2, /*HINT: note the third argument*/ char *accum). 

Again, it must be recursive. Non-recursive solutions WILL receive negative points. Don’t submit a non-recursive solution. 

Example below including all parts (full details will be out tomorrow):
