For the data of Exercise 12.11, compute all possible indices of dispersion. Which index would you choose and why? Exercise 12.11 The number of disk I/O’s performed by a number of programs were measured as follows: {23, 33, 14, 15, 42, 28, 33, 45, 23, 34, 39, 21, 36, 23, 34, 36, 25, 9, 11, 19, 35, 24, 31, 29, 16, 23, 34, 24, 38, 15, 13, 35, 28}. Which index of central tendency would you choose and why?

The performance of a remote procedure call ( RPC ) mechanism was compared on two operating systems named UNIX and ARGUS. The performance metric was total elapsed time, which was measured for various data sizes. The measurements are shown in Table 14.2. The scatter diagrams of the two data sets along with the regression lines are shown in Figures 14.3 and 14.4 for UNIX and ARGUS, respectively. Notice that for large data sizes the variance of both data sets is large. This is because ARGUS measurements are affected by the garbage collection and UNIX measurements are affected by a page optimization technique that avoids copying of complete data pages by mapping the pages from the input buffer into the kernel instead of the normal copying. Ignoring this discrepancy for the moment, the best linear models are

Using the NETLAB+ virtual environment , complete the following Lab. Ensure you have read the Preparation information, too. It is strongly suggested that you open the Lab Instructions in one window and the virtual devices in another and arrange them side by side so you may read the instructions in one window and type the commands in the other. Using the NETLAB+ virtual environment (on the VCASTLE servers), complete the following Lab: Unit 2 Lab 1 Instructions Directions : As you complete the Lab Instructions, upload your completed script into the Dropbox for below. Make sure your Get-Help function works properly and be sure to include all comments. Prepare your Unit 2 Lab 1 in a document named Lastname_U2_Lab1.ps1 . Submit your file using the upload instructions below. Document Preview: UNIT 2 LAB 1 INSTRUCTIONS: WRITING A BASIC SCRIPT
OVERVIEW
Most scripts are written using a common architecture. This architecture is designed to make
scripts easy to understand, modify, and debug. In this lab, you will create a script that uses the
basic script architecture that you may easily modify for use in future projects.
OBJECTIVES
4.5. Create meaningful comments in a script
4.6. Write a basic script template that contains the basic parts of a script.
5.1. Use input and output commands.
PREREQUISITES
A virtual machine with Windows 8.1 or newer or Windows Server 2012 R2 installed.
SCENARIO
Your organization is investigating the use of the command line and scripting for network
administration. It has been decided that scripting will be used extensively and that a basic
template that contains an organized architecture and some preconfigured information would
be useful.
TASKS
Many parts of a script such as organization, comments, and help documentation are redundant.
To make scripting more efficient, we will create a script template that contains this redundant
information.
CREATING A SCRIPT TEMPLATE
CREATING COMMENT BASED HELP DOCUMENTATION
1. Start your server virtual machine.
2. For these steps, you will need to login using the administrator account.
3. Create the folder C:usersadministratorscripts for your scripts.UNIT 2 LAB 1 INSTRUCTIONS: WRITING A BASIC SCRIPT
4. Open the PowerShell ISE.
a. In the script pane, type the following:

5. Save the file as template.ps1… Attachments: CIS321-U2-Lab….pdf

a) The signal power for a particular class of network wiring is 2898dB and the noise rating at that particular signal strength at 100MHz is 40dB. Find the signal-tonoise ratio for this conductor. b) Suppose the noise rating for the network wiring in Part a is 0.32 dB and the noise rating is 35 dB when a 200MHz signal is transmitted. What is the signal strength?

Answer the following for the data of Exercise 12.11: a. What is the 10-percentile and 90-percentile from the sample? b. What is the mean number of disk I/O’s per program? c. What is the 90% confidence interval for the mean? d. What fraction of programs make less than or equal to 25 I/O’s and what is the 90% confidenceinterval for the fraction? e. What is the one-sided 90% confidence interval for the mean? Exercise 12.11 The number of disk I/O’s performed by a number of programs were measured as follows: {23, 33, 14, 15, 42, 28, 33, 45, 23, 34, 39, 21, 36, 23, 34, 36, 25, 9, 11, 19, 35, 24, 31, 29, 16, 23, 34, 24, 38, 15, 13, 35, 28}. Which index of central tendency would you choose and why?

For the code size data of Table 11.2, find the confidence intervals for the average code sizes on various processors. Choose any two processors and answer the following: a. At what level of significance can you say that one is better than the other? b. How many workloads would you need to decide the superiority at 90% confidence?
