In your own words, explain the process undertaken while testing the significance of a multiple linear regression model parameter Indicating clearly the hypothesis considered, test statistics used rejection criteria and conclusion.​

Answers

Answer 1
Multiple Linear Regression Analysis consists of more than just fitting a linear line through a cloud of data points. It consists of three stages: 1) analyzing the correlation and directionality of the data, 2) estimating the model, i.e., fitting the line, and 3) evaluating the validity and usefulness of the model.

1. Where did the Industrial Revolution start and why did it begin there?​

Answers

Answer:

The first Industrial Revolution began in Great Britain in the mid-to-late 1700s, when innovation led to goods being produced in large quantities due to machine manufacturing.

This process began in Britain in the 18th century and from there spread to other parts of the world. Although used earlier by French writers, the term Industrial Revolution was first popularized by the English economic historian Arnold Toynbee (1852–83) to describe Britain's economic development from 1760 to 1840.

Consider the following class. public class ClassicClass { private static int count = 0; private int num; public ClassicClass() { count++; num = count; } public String toString() { return count + " " + num; } } What is printed when the following code in the main method of another class is run? ClassicClass a = new ClassicClass(); ClassicClass b = new ClassicClass(); ClassicClass c = new ClassicClass(); System.out.println(a + ", " + b + ", " + c);

Answers

The the code in the main method is run, it will print

"3 1, 3 2, 3 3"

The static/class field count stores the number of instances of the class created. count is always incremented when the instance constructor is called.

The instance field num acts like an identifier/serial number for the instance created. When the constructor is called, the current count is stored in the num field of the instance.

Each instance's toString( ) method will output the total count (from count) and the serial of the instance (from num).

When the code runs in the main method, it creates three instances (making count==3), so that we have

a = {count: 3, num: 1}b = {count: 3, num: 2}c = {count: 3, num: 3}

and implicitly calls toString( ) in the println method for each of the three instances to produce the following output

"3 1, 3 2, 3 3"

Write the function void sort2(double* p, double* p) that receives two pointers and sorts the values to which they point. To test the function, write the main function that prompts the user to enter two values and then print out the sorted values. If you call sort2(&x, &y) then x <= y after the call.

Answers

The function illustrates the use of pointers.

Pointers are used to store address in programming languages such as C and C++.

The program in C language where comments are used to explain each line is as follows:

#include <stdio.h>

//This defines the function

void sort2(double* p1, double* p2){

   //This declares a temporary variable t

double t;

//If p2 is less than p1,

if (*p2 < *p1) {

    //The next 3 lines swap their values

    t = *p2;

    *p2 = *p1;

    *p1 = t;

}

//This prints p1

printf("%f ", *(p1));

//This prints p2

printf("%f ", *(p2));

}

//The main method to test the function begins here

int main(){

double x = 23.0;

double y = 14.1;

sort2(&x, &y);

return 0;

Just a quick question, how do you set something == to char and int in an if statement (java)
Write a method checkCharacter() which has 2 parameters: A String, and a specified index (an int). Method checkCharacter() checks the character at the specified index of the String parameter, and returns a String based on the type of character at that location indicating if the character is a letter, digit, whitespace, or unknown character.


Ex: The method calls below with the given arguments will return the following Strings:


checkCharacter("happy birthday", 2) returns "Character 'p' is a letter"

checkCharacter("happy birthday", 5) returns "Character ' ' is a white space"

checkCharacter("happy birthday 2 you", 15) returns "Character '2' is a digit"

checkCharacter("happy birthday!", 14) returns "Character '!' is unknown"


Your program must define the method:

public String checkCharacter(String word, int index)



this is what i got to but im stuck on how to find out if its a char or int


public class TollCalculation {


public double calcToll(int hour, boolean isMorning, boolean isWeekend) {

int timeHour; // Time of travel hour (24 hour format)

int timeMinute; // Time of travel minute

int inputColon; // Used to read time format

String userInput; // User specified time

double tollAmount;

}


public static void main(String[] args) {

TollCalculation tollObj = new TollCalculation();


// Test the three samples from the specification.

System.out.println(tollObj.calcToll(7, true, false));

System.out.println(tollObj.calcToll(1, false, false));

System.out.println(tollObj.calcToll(3, true, true));

}

}

Answers

This is the requested code in java.

public class CharTest {

   public static String checkCharacter(String text, int index) {

       if (0 <= index && index <= text.length()) {

           char ch = text.charAt(index);

           if (Character.isLetter(ch)) {

               return ch + " is a letter";

           } else if (Character.isDigit(ch)) {

               return ch + " is a digit";

           } else if (Character.isWhitespace(ch)) {

               return ch + " is a whitespace character";

           } else {

               return ch + " is an unknown type of character";

           }

       } else {

           return "index " + index.toString() + " is out of range";

       } // end if

   } // end function checkChar()

   public static void main(String[] args) {

       // Test the three samples from the specification.

       System.out.println(checkCharacter("happy birthday", 2));

       System.out.println(checkCharacter("happy birthday", 5));

       System.out.println(checkCharacter("happy birthday 2 you", 15));

   } // end function main()

} // end class CharTest

The function checkcharacter(text, index) returns a string value describing the kind of character found at the position in text specified by index; whether it was a letter, digit, whitespace, or an unknown kind of character.

How it does that is to make use of respective functions defined within the Character class in java. That is

isLetter(char) returns a bool specifying if the char parameter is a letter.isDigit(char) returns a bool specifying if the char parameter is a digit.isWhitespace(char) returns a bool specifying if the char parameter is a whitespace character.

It calls these functions in an if statement. These else part of the if statement is then executed if the character is neither a letter, digit, or whitespace.

Finally, the function main() calls checkCharacter() three times to test the function and return the results to the console.
