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?

a.) Compute the statistic selected:

b.) Compute the appropriate test statistic(s) to make a decision about H₀.
(Hint: Make sure to write down the null and alternative hypotheses to help solve the problem.)
Critical value =

Make an interpretation based on the results.

More weight of individuals on the diet significantly predicts more body fat.

The weight of individuals on the diet does not significantly predict body fat.

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.

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] + " ");
}
}

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.)
