There is one attachment to this message: § Sample Exercises – Chapter 1 (for your review) Your first week assignments are as follows: 1. Download and read the syllabus. Let me know your questions.2. Add-in Excel’s Data Analysis ToolPak. If your Excel does not have it already (see the Syllabus). 3. Review/learn Excel’s Data Analysis ToolPak. 4. Read/learn Chapter 1. 5. Review sample exercises of Chapter 1.6. Complete homework exercises: number 1-7 on page 5, 1-25 on page 18, 1-34 on page 18, and 1-39 on page 19. Type your answers in MS Word following the same format I have used in Solution to Sample Exercises.
Hint: For exercise 1-39, you go to:
Data Analysis
Random Number Generation
Number of Variables: 5
Number of Random Numbers: 8
Parameters:
- 578
Output Range: $A$1
Here, I am choosing 5 columns and 8 rows to get 40 random numbers. You may choose other number as long as they multiply to 40.

A bar chart is used whenever you want to display data that has already been categorized while a histogram is used to display data over a range of values for the factor under consideration. Another fundamental difference is that there typically are gaps between the bars on a bar chart but there are no gaps between the bars of a histogram.
Page 5 – Number 1-7 (This is also a homework exercise; do solve it yourself)
The appropriate chart in this case is a histogram where the horizontal axis contains the number of missed days and the area of the bars represent the number of employees who missed each number of days.
Note: Leave no gap between the bars.

To determine the range of employee numbers for the first part selected in a systematic random sample use the following:
Part range =
Thus, the first employee selected will come from parts 1-180. Once that employee number is randomly selected, the second employee will be the one numbered 100 higher than the first, and so on.

- The population should be all users of cross-country ski lots in Colorado.
- Several sampling techniques could be selected. Be sure that some method of ensuring randomness is discussed. In addition, some students might give greater weight to frequent users of the lots. In which case the population would really be user days rather than individual users.
- Students using Excel should use the Data, Data Analysis, Random Number Generation. Students’ answers will differ since Excel generates different streams of random numbers each time it is used. Since the application requires integer numbers, the Decrease Decimal option should be used.

String Input Console Application and Program Analysis
String Input Console Application and Program Analysis
Order details
Instructions
You are provided with a simple C++ console application that will write a program that will take string input from a user (See .cpp attachment). The program should reverse the string and then print the output to the screen. Take input from the user 3 times for varying string lengths. For this paper, you will analyze the program and discuss and identify the possible vulnerabilities that may exist. If present, discuss solutions to minimize the vulnerabilities. Then discuss and identify possible problems that can result in errors for string manipulation of data. The program analysis should be 2 pages in length and
following the APA guidelines. In addition to my program, I have attached detailed instructions, my lecture notes, and an example essay as a guideline. You should include at least one source from professional or academic literature, such as articles from peer-reviewed journals and relevant textbooks.
For this paper, the use of Wikipedia is not considered an academic or professional reference. You should also ensure to proofread and spell-check your responses. All sources should be formatted using APA guidelines. Contact me with any questions.
