Answer:

Normalization

Explanation:

Converting a poorly-structured table and optimizing its database structure in order to reduce redundancy in relations can be referred to as database normalization. If the data is not redundant means that data inconsistencies and errors like deletion and insertion will get reduced or eliminated significantly.

Find a 95% confidence interval for the mean failure pressure for this type of roof panel.The article "Wind-Uplift Capacity of Re

aliya0001 [1]

Answer:

The 95% confidence interval would be given by (2.351;3.525)

Explanation:

1) Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

$\bar X$ represent the sample mean

$\mu$ population mean (variable of interest)

s represent the sample standard deviation

n represent the sample size

2) Confidence interval

The confidence interval for the mean is given by the following formula:

$\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}$ (1)

In order to calculate the mean and the sample deviation we can use the following formulas:

$\bar X= \sum_{i=1}^n \frac{x_i}{n}$ (2)

$s=\sqrt{\frac{\sum_{i=1}^n (x_i-\bar X)}{n-1}}$ (3)

The mean calculated for this case is $\bar X=2.938$

The sample deviation calculated $s=0.472$

In order to calculate the critical value $t_{\alpha/2}$ we need to find first the degrees of freedom, given by:

$df=n-1=5-1=4$

Since the Confidence is 0.95 or 95%, the value of $\alpha=0.05$ and $\alpha/2 =0.025$ , and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-T.INV(0.025,4)".And we see that $t_{\alpha/2}=2.78$

Now we have everything in order to replace into formula (1):

$2.938-2.78\frac{0.472}{\sqrt{5}}=2.351$

$2.938+2.78\frac{0.472}{\sqrt{5}}=3.525$

So on this case the 95% confidence interval would be given by (2.351;3.525)

Write a program that prompts the user to enter three cities and displays them in ascending order. Here is a sample run: Enter th

maria [59]

Answer:

import java.util.Scanner;

public class SortStrings3 {

public static void main(String args[]){

Scanner scanner = new Scanner(System.in);

String str1, str2, str3;

System.out.print("Enter the first city: ");

str1 = scanner.nextLine();

System.out.print("Enter the second city: ");

str2 = scanner.nextLine();

System.out.print("Enter the third city: ");

str3 = scanner.nextLine();

System.out.print("The three cities in alphabetical order are ");

if(str1.compareTo(str2) < 0 && str1.compareTo(str3) < 0){

System.out.print(str1+" ");

if(str2.compareTo(str3) < 0){

System.out.print(str2+" ");

System.out.println(str3);

}

else {

System.out.print(str3+" ");

System.out.println(str2);

}

else if(str2.compareTo(str1) < 0 && str2.compareTo(str3) < 0){

System.out.print(str2+" ");

if(str1.compareTo(str3) < 0){

System.out.print(str1+" ");

System.out.println(str3);

}

else {

System.out.print(str3+" ");

System.out.println(str1);

}

else{

System.out.print(str3+" ");

if(str1.compareTo(str2) < 0){

System.out.print(str1+" ");

System.out.println(str2);

}

else {

System.out.print(str2+" ");

System.out.println(str1);

}

EXPLANATION:

Okay, we are given that a program should be written which will make user to enter three cities namely Atlanta, Chicago and Los Angeles (which should be done in ascending alphabetical order).

So, we will be writting the code or program with a programming language known as JAVA(JUST ANOTHER VIRTUAL ACCELERATOR).

We will make use of java to write this program because Java can be used in Loading code, verifying codes and executing codes on a single or multiple servers.

The code or program can be seen in the attached file/document. Kindly check it.
