Explanation:

At a large university, 20% of a random sample of male students have an overall grade point average (GPA) of 3.5 or higher. A random sample of female student records found that 25% had a GPA of 3.5 or higher. The president of the university wants to determine whether there is evidence of a difference in grades between males and females. What would she write as the null and alternative hypotheses for this situation?
Answer choices
H0:p1 − p2 = 0 and Ha:p1 − p2 ≠ 0
H0:p1 − p2 = 0 and Ha:p1 − p2 > 0
H0:p1 − p2 = 0 and Ha:p1 − p2 < 0
H0:p1 − p2 > 0 and Ha:p1 − p2 = 0
H0:p1 − p2 > 0 and Ha:p1 − p2 ≠ 0

Answers

Answer:

H0:p1 − p2 = 0 and Ha:p1 − p2 ≠ 0

Explanation:

Null hypothesis would be there not being a difference, so the difference would be 0.

Alternative hypothesis would be that there is a difference. However, the president of the university does not want to determine whether more males than females, or more females than males, get a GPA of 3.5 or higher, so the alternative hypothesis is =/= 0.

A special interest group wants the federal government to increase pollution controls on manufacturing plants.

(A) Describe how the free-rider effect will affect the group's success.

(B) In the context of the scenario, explain how the interest group will attempt to influence the legislative process.

(C) In the context of the scenario, explain why the interest group might try to seek its policy goals through the bureaucracy rather than through Congress.

Answers

Answer:

Here's what I put. I don't have a grade yet but I've been getting almost all 100%'s.

Explanation:

A) The free-rider effect is defined as a "type of market failure that occurs when those who benefit from resources, public goods (such as public roads or hospitals), or services of a communal nature do not pay for them[1] or under-pay. Free riders are a problem because while not paying for the good (either directly through fees or tolls or indirectly through taxes), they may continue to access or use it. Thus, the good may be under-produced, overused or degraded." This effect will negatively affect the group's success because the government is happy to look the other way and collect the tax benefits (among other things) that the factories give the government. The government benefits from the factories, so they wouldn't really have an incentive to take the group seriously.

B) The interest group might try to influence the legislative process by convincing multiple different representatives in Congress to support their idea and/or introduce the idea as a bill. If they get enough of them to support their idea, they will have a few guaranteed votes, and there will be a larger chance that more representatives will support this idea.

C) The interest group might try to seek its policy goals through the bureaucracy rather than through Congress because their idea doesn't necessarily need to be a law. The higher-up government officials in multiple different areas are the ones who are able to make the most difference because there isn't the issue of a divided House and Senate. They can also usually make changes much more quickly than Congress can

Ocean tides are predictable because

the orbit of the moon and Earth, as well as the rotation of the Earth are well known.

The same side of the moon always faces the Earth.


The Earth revolves around the moon in a predicable pattern.

The sun revolves around the Earth in a predictable pattern.

Answers

Answer: the orbit of the moon and Earth, as well as the rotation of the Earth are well known.

Explanation:

Tides are as a result of the gravitational impact of both the Sun and the Moon on the Earth. Indeed, not only the ocean experiences this effect as land does too but because the water is more fluid, it reacts more thereby causing tidal waves in the oceans and seas.

Because we know the rotation of the Earth and the orbit of the moon however (and therefore when a certain part of the Earth will be imparted by the Sun or the Moon), we are able to predict these tidal waves with high accuracy.
