Answer:
The answer is- Test of two proportions
Explanation:
A test for two proportions is used to compare two proportions in order to see if they are the same. it is used when comparing the percentages of two groups. Like in the question, the marriage counselor is checking to see if the percentage of communicative couples whose marriage ended separation or divorce was greater than the percentage of non-communicative couples whose marriage ended in separation or differences.
The two different proportions are the communicative and non-communicative couples.
Answer:
One of the first in the late 17th century, the English thinker John Locke (1632-1704) spoke about human rights; he believed that everyone from birth has the right to life, property, and freedom. The guarantors of these rights are firm laws and separation of powers. Supporters of John Locke in the school of natural law justified their theories with references to nature or God. But in this case, it is not the flawlessness of the substantiation of human rights that is important, but the fact that this issue was understood as socially significant - humanity has risen to the level of self-awareness, which recognizes the value of each "Self" and the equivalence of people's interests.

Answer:
Osha require employers to construct and install the following to minimize electrocution hazards:
- Insulators
- Guarding Systems
- Grounding Systems
-Circuit protection devices
Explanation:
Imsulators
- Insulators are materials that do not conduct electricity. They are used to coat metals and other conductors to prevent or reduce the possibility of current flow that can cause electrocution.Example of insulators include rubber,mica, plastics e.t.c.
- Guarding System
Guarding systems basically involves granting restricted access to electrical equipments especially those operating at 50 volts and above.Guarding can be achieved by placing electric equipments in restricted areas or even enclosing them. A conspicuous warning label is usually place in such areas where the electric eqipment is situated.
- Grounding System
A grounding system serves to create a path of low resistance from the electric equipment to the earth so that excess voltage build up on the eqipment is prevented as it will be discharged through the created path of low resistance to the earth. The grounding system is essentially a secondary protective measure.It does not guarantee against electrocution.
-Circuit Protection devices
Circuit protection devices serve to reduce or completely obstruct current flow when there is overload,ground fault or a short circuit in the electric system wiring.Example of these devices include circuit breakers, fuses, ground-fault circuit interrupters and arc-fault circuit interrupters.
It was because the rogues shot at them right as he fired.
Taking a direct quote from the book:
"However, we had no luck; for just as Trelawney fired, down he stooped, the ball whistled over him, and it was one of the other four who fell."
Basically, the rogues shot, so Trelawney had to stoop down to avoid a shot from the rogues, which threw off his aim.
