Suppose, household color TVs are replaced at an average age of μ = 8.4 years after purchase, and the (95% of data) range was from 5.0 to 11.8 years. Thus, the range was 11.8 – 5.0 = 6.8 years. Let x be the age (in years) at which a color TV is replaced. Assume that x has a distribution that is approximately normal. (a) The empirical rule indicates that for a symmetrical and bell-shaped distribution, approximately 95% of the data lies within two standard deviations of the mean. Therefore, a 95% range of data values extending from μ – 2σ to μ + 2σ is often used for "commonly occurring" data values. Note that the interval from μ – 2σ to μ + 2σ is 4σ in length. This leads to a "rule of thumb" for estimating the standard deviation from a 95% range of data values. Estimating the standard deviation For a symmetric, bell-shaped distribution, standard deviation ≈ range 4 ≈ high value – low value 4 where it is estimated that about 95% of the commonly occurring data values fall into this range. Use this "rule of thumb" to approximate the standard deviation of x values, where x is the age (in years) at which a color TV is replaced. (Round your answer to one decimal place.) yrs (b) What is the probability that someone will keep a color TV more than 5 years before replacement? (Round your answer to four decimal places.) (c) What is the probability that someone will keep a color TV fewer than 10 years before replacement? (Round your answer to four decimal places.) (d) Assume that the average life of a color TV is 8.4 years with a standard deviation of 1.7 years before it breaks. Suppose that a company guarantees color TVs and will replace a TV that breaks while under guarantee with a new one. However, the company does not want to replace more than 6% of the TVs under guarantee. For how long should the guarantee be made (rounded to the nearest tenth of a year)? yrs

A clinic developed a diet to impact body mass (fat and muscle). A nutritionist in the clinic hypothesizes that heavier individuals on the diet will predict more body fat. Below are the data for a sample of clients from the clinic. Weight is measured in kilograms (kg) and percentage body fat is estimated through skinfold measurement. What can the nutritionist conclude with α = 0.01?

Write a java program, creating three threads, to sort two arrays and merge them into a third array. More specifically:

Create a thread to sort the first array. Create a thread to sort the second array. Create a thread to merge the arrays into the third array. Let the main method prints the merged array.

i want three threads to be created .

You must call the two sorter threads together. In other words, if we name these threads sorta, sortb, and merge, you must call the start methods in the following sequence: sorta.start(); sortb.start(); Some java code merge.start();

I post the sequential program for this assignment. Note that you need to change the classes Sorter and Merger to make them suitable for threads.

import java.util.Random;

public class Main{
public static void main(String[] args) {
Random rand = new Random();
int size = rand.nextInt(50) + 1;
int a[] = new int[size];
size = rand.nextInt(50) + 1;
int b[] = new int[size];
for(int i = 0; i < a.length; i++)
a[i] = rand.nextInt(999);
for(int i = 0; i < b.length; i++)
b[i] = rand.nextInt(999);
new Sorter(a);
new Sorter(b);
int[] c = new int[a.length + b.length];
new Merger(a, b, c);
for(int i = 0; i < c.length; i++)
System.out.print(c[i] + " ");
}
}

-------------------------------------------------------------------

public class Merger{
public Merger(int[]a, int[] b, int[] c){
merge(a, b, c);
}

private void merge(int[] a, int[] b, int[] c){
int index = 0, i = 0, j = 0;
while(i < a.length && j < b.length)
if(a[i] < b[j])
c[index++] = a[i++];
else
c[index++] = b[j++];
if(i < a.length)
for(int k = i; i < a.length; i++)
c[index++] = a[i];
if(j < b.length)
for(int k = j; j < b.length; j++)
c[index++] = b[j];
}
}
----------------------------------------------------------------------------------------------------------------

public class Sorter{
public Sorter(int[] a){
sort(a);
}

private void sort(int[] a){
for(int i = 0; i < a.length; i++){
int pos = i;
int min = a[i];
for (int j = i + 1; j < a.length; j++)
if(a[j] < min){
min = a[j];
pos = j;
}
a[pos] = a[i];
a[i] = min;

On planet Tehar, the free-fall acceleration is the same as that on Earth, but there is also a strong downward electric field that is uniform close to the planet's surface. A 1.86-kg ball having a charge of 5.04 μC is thrown upward at a speed of20.1 m/s. It hits the ground after an interval of 4.10 s. What is the potential difference between the starting point and the top point of the trajectory? (Use 9.8 m/s2 for the acceleration due to gravity.)
