The question is not influenced by the fact that it's about intelligence -  standard deviation is a way of describing data and it's the same for all kinds of data.

So in general, one  standard deviation away from the mean in both directions encompases around 66% of the cases - so here it would be 66% of children.

Additionally, 95% of all children should lie withing two standard deviations - so two standard deviations below or above the average.

Write a program, NumberStatistics.java, that reads an unspecified number of integers. The program ends with the input 0. The pro
Lerok [7]

Answer:

Following are the program, which can be below:

import java.util.*; //defining header file

public class NumberStatistics  //defining class NumberStatistics

{

public static void main(String[] arc) //defining main method

{

int total_number=0,max_val=0,min_val=0,neg_val=0,pos_val=0,neg_count=0,pos_count=0,x; //defining variables

Scanner ox= new Scanner(System.in); //creating Scanner class Object

System.out.println("Enter positive and negative value with sign and when complete inter 0:"); //print message  

x= ox.nextInt(); //input value from user

while(x!=0) //defining loop to check input value is 0

{

total_number++; // increment value

if(total_number == 1)  //defining conditional statement to check minimum and maximum value

{

max_val = x; //assign value in max  

min_val = x;//assign value in min

}

else  //defining else block

{

if(max_val < x) //check maximum value

{

max_val = x; //assign maximum value

}

if(min_val > x) //check minimum value

{

min_val = x; //assign minimum value

}

}

if(x > 0) //input values  

{

pos_count++; //count positive value

pos_val+=x; // add positive values

}

else  

{

neg_count++;//count negative value

neg_val+=x; // add negative values

}

x = ox.nextInt(); //input values

}

// defining conditionl statement

if(total_number != 0)  // defining if block to print all value

{

System.out.println("positive value average= "+(pos_val/(double)pos_count));

System.out.println("negative values Average= "+(neg_val/(double)neg_count));

System.out.println("all values average= "+(pos_val+neg_val)/(double)total_number);

System.out.println("maximum value = "+max_val+"\n"+" minimum value = "+min_val);

}

else  

{

System.out.println("no positive values found");

System.out.println("no negative values found");

}

}

}

Output:

Enter positive and negative value with sign and when complete inter 0:

12

8

04

22

-22

-5

9

0

positive value average= 11.0

negative values Average= -13.5

all values average= 4.0

maximum value = 22

minimum value = -22

Explanation:

The Description of the above java program can be described as follows:

  • In the above code first we import the package for user input, then defines the variable "total_number,max_val,min_val,neg_val,pos_val,neg_count, pos_count,x" to store the value prints its value.
  • In the next step, a scanner class object is created for user input and defines a while loop, that checks input value isn't equal to 0, inside the loop a conditional statement defines that cont and calculates all positive, negative, and all values addition.
  • At the another conditional statement is defines, that prints all value average, and also prints maximum, minimum value.

miss Akunina [59]

Answer:

See explanation below.

Explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question follows:

Suppose you are among those who believe that the NLRA should be transformed. What arguments support the claim that a complete overhaul is necessary? What alternative models might be considered as a replacement for the NLRA model of exclusive representation?

The explanation of the answers is now provided as follows:

a. What arguments support the claim that a complete overhaul is necessary?

The adversarial nature of labor relations in the United States, which many claim is produced by the National Labor Relations Act's (NLRA)'s very existence, is the fundamental reason for its transformation. In a global economy, supporters of transformation say that adversarialism is undesirable for employees and employers because it makes representation and profit maximization more difficult. The principles of exclusive representation and majority support are specific aspects of the NLRA that promote adversarialism.

The fact that it is compulsory for a union to win the support of a majority of workers, the process of representation results into a tone of a "u versus. them". As a result, both sides try to make the other look bad in the eyes of the employees who will vote.

Based on the above, a  complete overhaul is necessary.

b. What alternative models might be considered as a replacement for the NLRA model of exclusive representation?

Giving nonmajority unions legal protection by requiring employers to negotiate with them is one alternative to replace the NLRA model of exclusive representation. Under this, the contracts would not cover all employees; only those who are union members would be covered.

Another alternative is that work councils could also be used to supplement or replace the certification process. Employee free speech rights, wrongful dismissal procedures, employee participation on business boards of directors, and the right to workplace information are all potential transformation factors that might be taken into consideration.
