Many fast-food restaurants use automatic soft-drink dispensing machines that fill cups once an order is placed at a drive-through window. A regional manager for a fast-food chain wants to determine if the machines in her region are dispensing the same amount of product. She samples four different machines and measures a random sample of 16-ounce drinks from each machine. Here is the data she collects (in ounces):

a) “Number of ounces” is a quantitative variable. Is it discrete or continuous?

b) “Number of ounces” is what level of measurement?

c) Is this a designed experiment or an observational study? Briefly explain.

d) At the 5% Level of Significance, determine whether or not the data indicate that the mean amount dispensed from the machines is not the same, by doing each of the following:

            1) Write the Hypotheses.

2) Use your calculator to do a one-way ANOVA test. Explain in some detail how the results of the test lead you to reject or not reject the null hypothesis.

3) Write a formal conclusion.

e) Using the language of our textbook on bias, name at least one type of bias that might be present in this research. Briefly explain.

Assignment; For this component, you will write a report or critique on the paper you chose from Assignment 1. Your report should be limited to approx. 1500 words (not including references).

Use 1.5 spacing with a 12 point Times New Roman font. Though your paper will largely be based on the chosen article, you should use other sources to support your discussion or the chosen papers premises.

Citation of sources is mandatory and must be in the IEEE style.

TOPIC: Social Engineering and phishing attacks

Your report or critique must include: Introduction: Identification of the paper you are critiquing/ reviewing, a statement of the purpose for your report and a brief outline of how you will discuss the selected article (one or two paragraphs).

Body of Report: Describe the intention and content of the article. If it is a research report, discuss the research method (survey, case study, observation, experiment, or other method) and findings. Comment on problems or issues highlighted by the authors. Report on results discussed and discuss the conclusions of the article and how they are relevant to the topics of this Unit of Study.

3 Conclusion: A summary of the points you have made in the body of the paper. The conclusion should not introduce any ‘new’ material that was not discussed in the body of the paper. (One or two paragraphs) References: A list of sources used in your text. They should be listed alphabetically by (first) author’s family name. Follow the IEEE style.

Can you please rewrite this Java code so it can be better understood.

I am having an issue with the code. The issue I am having removing the part when it asks the tuter if he would like to do teach more. I want the program to stop when the tuter reaches 40 hours. I believe the issue I am having is coming from the driver.

Question 2:

Translation is another name for protein synthesis. There are three steps that take place repeatedly during elongation.

a) Give the name and a short description of what happens during the first step of elongation during translation?

b) Give the name and a short description of what happens during the second step of elongation during translation?

C) Give the name and a short description of what happens during the third step of elongation during translation?

Please help! Thanks

Write an application that allows a user to enter the names and birthdates of up to 10 friends. Continue to prompt the user for names and birthdates until the user enters the sentinel value ZZZ for a name or has entered 10 names, whichever comes first. When the user is finished entering names, produce a count of how many names were entered, and then display the names. In a loop, continuously ask the user to type one of the names and display the corresponding birthdate or an error message if the name has not been previously entered. The loop continues until the user enters ZZZ for a name. Save the application as BirthdayReminder.java.

My issue in this is the loop portion. I am not sure if I have done it properly. I also need help trying to comment this code so I can explain it better. Could someone help analyze my code so that I can properly do this JAVA assignment? Please include comments as well inside the code.

Here is what I have so far:

import java.util.*;

public class BirthdayReminder{

public static void main(String[] args)

{

final int NUM_NAMES = 10;

String sentinal = "ZZZ";

int count = 0;

String name = null;

String birthdate = null;

String[] names = new String[NUM_NAMES];

String[] birthdates = new String[NUM_NAMES];

Scanner input = new Scanner(System.in);

System.out.println("Enter a name or " + sentinal + " to quit > ");

name = input.nextLine();

while(name.compareTo(sentinal)!=0 && count < NUM_NAMES)

{

System.out.println("Enter birthdate (mm/dd) > ");

birthdate = input.nextLine();

names[count] = name.trim();

birthdates[count] = birthdate.trim();

System.out.println("Enter a name or " + sentinal + " to quit > ");

name = input.nextLine();

++ count;

}

System.out.println("\nCount of names is " + count);

System.out.println("\nNames are:" + count);

for(int x = 0; x < count; ++x)

System.out.println(names[x]) ;

boolean repeat = true;

boolean found;

while(repeat)

{

found=false;

System.out.println("\nEnter a name or " + sentinal + " to quit > ");

name = input.nextLine().trim();

if(name.compareTo(sentinal)==0)

repeat = false;

else

{

for(int x = 0; x < count; ++x)

{

if(names[x].compareTo(name)==0)

{

found =true;

birthdate = birthdates[x];

break;

}

}

if(found)

System.out.println("Birthdate of " + name + " is " + birthdate);

else

System.out.println("Birthdate of " + name + " is not found");

}

}

}

}
