At an early stage of clinical trials of a certain method of gender​ selection, 14 couples using that method gave birth to 13 boys and 1 girl. Complete parts​ (a) through​ (e) below.

a. Assuming that the method has no effect and boys and girls are equally​ likely, use the range rule of thumb to identify the limits separating values that are significantly low and those that are significantly high​ (for the number of boys in 14 ​births). Based on the​ results, is the result of 13 boys significantly high​?

Significantly low values for the number of boys in 14 births are _____ and lower. Significantly high values for the number of boys in 14 births are ____ and higher. The result of 13 boys (is or is not?) significantly high. ​(Type integers or decimals rounded to one decimal place as​ needed.)

b. Find the probability of exactly 13 boys in 14 ​births, assuming that the method has no effect. _______ ​(Type an integer or decimal rounded to six decimal places as​ needed.)

c. Find the probability of 13 or more boys in 14 ​births, assuming that the method has no effect. _____ ​(Type an integer or decimal rounded to six decimal places as​ needed.)

d. Which probability is relevant for determining whether 13 boys is significantly high​: the probability from part​ (b) or part​ (c)? Based on the relevant​ probability, is the result of 13 boys significantly high​?

The probability from (Part C or Part B) is relevant for determining whether 13 boys is significantly high. Based on this​ probability, the result of 13 boys (is or is not) significantly high.

e. What do the results suggest about the effectiveness of this method of gender​ selection?

A. The results do not suggest anything about the effectiveness of this method of gender selection.

B. The results suggest that this method is not effective at transforming the distribution of genders to a binomial distribution.

C. The results suggest that this method is effective at transforming the distribution of genders to a binomial distribution. D. The results suggest that this method is not effective in increasing the likelihood that a baby is a boy.

E. The results suggest that this method is effective in increasing the likelihood that a baby is a boy.

1. Several forces act on an object at rest. It is known that the sum of the forces acting on the object is zero. Which statement is necessarily true?
A) The object will remain stationary.
B) The object's center of mass may move in such a way that the object will roll without slipping.
C) The object's center of mass will not move, but the object may begin to rotate.
D) The object's center of mass may accelerate and the object may begin to rotate.
E) The object's center of mass may accelerate, but the object will remain in the same orientation.

2. A heavy boy and a lightweight girl are balanced on a massless seesaw. If they both move forward so that they are one-half their original distance from the pivot point, what will happen to the seesaw?
A) It is impossible to say without knowing the masses.
B) It is impossible to say without knowing the distances.
C) The side the boy is sitting on will tilt downward.
D) Nothing, the seesaw will still be balanced.
E) The side the girl is sitting on will tilt downward.

A) elastic region.
B) proportional region.
C) plastic region.
D) ultimate strength region.
E) breaking region.

6. The maximum elongation of a typical metal is reached at the
A) proportional limit.
B) elastic limit.
C) inelastic limit.
D) breaking point.
E) ultimate strength.

7. Strain is

An LED is connected to PD3 and a Button is connected to PD0. Write a C program that will wait for the button to be pressed and then released (make sure you debounce the press and release). Each time the button is pressed, the LED blinks a number of times corresponding to how many times the button has been pressed and released. For example, when the button is pressed and released for the first time, the LED will blink once; and when the button is pressed and released the second time, the LED will blink twice, etc. The button will be pressed once and release once each time. The LED shows a count (accumulated number of times Button was pressed).

Use a sentinel while loop that repeatedly prompts the user to enter a number, once -1 is entered, stop prompting for numbers and display the maximum number entered by the user.

I am struggling to have my program print the math function. Here is what I have so far:

import java.util.*;
public class MaxSentinel
{
public static void main(String[] args)
{
  
Scanner input = new Scanner(System.in);
System.out.println("Please enter a value. Press -1 to stop prompt.");
int number = 0;
do
{
System.out.println("Enter a value.");
number = input.nextInt();
}
while(number != -1);
  
  
}
}

The Supreme Court has defined public figures as those who have “voluntarily exposed

The Supreme Court has defined public figures as those who have “voluntarily exposed themselves to increased risk of injury by assuming an influential role in ordering society.” When deciding whether someone is a public figure, courts look at whether this person has received press coverage, sought the public spotlight, and has the opportunity to publicly rebut the accusations. Some have argued that social media makes anyone with a public Facebook profile or a certain number of Twitter followers a public figure. Do you agree? Should the Court revisit the definition of “public figure” in light of social media?

he article "Chances Are You Know Someone With a Tattoo, and He's Not a Sailor" (Associated Press, June 11, 2006) reported the following approximate probabilities based on a survey of 1000 adults ages 18 to 50:

P(age 18 to 29) = 0.50

P(tattoo) = 0.24

P(tattoo and age 18 to 29) = 0.18

Construct a contingency table and use your table to answer the following question.

What is the probability that a randomly selected 30 to 50 year old has a tattoo?

Write your answer as a percent rounded to the nearest tenth. Be sure to interpret your answer in a complete sentence.

I ranked the steam engine as one of the half dozen most important inventions in history – explaining how, even if obsolete nowadays, it was the first engine able to generate power, a technology that revolutionized our ability to do something we could never do before. Choose five other inventions you think would similarly round out the top half dozen, and make a good case as to how each merits the important position you gave it in the progress of science, technology, or society. Think historically and comprehensively.

inventions( Printing press, light bulb, telegraph, the wheel, microscope)

You represent a Canadian toy company that is negotiating to buy miniature truck wheels from a manufacturer in Osaka, Japan. In your first meeting, you explain that your company expects to control the design of the wheels as well as the materials that are used to make them. The manufacturer’s representative looks down and says softly, “Perhaps that will be difficult.” You press for agreement, and to emphasize your willingness to buy, you show the prepared contract you have brought with you. However, the manufacturer seems increasingly vague and uninterested.

What cultural differences may be interfering with effective communication in this situation? Explain.
