What is null hypothesis?</h3>
- Conjectures used in statistical tests, which are formal techniques for drawing conclusions or making judgments based on data, include the null hypothesis and the alternative hypothesis.
- The hypotheses, which are based on a sample of the population, are suppositions regarding a statistical model of the population. The tests are essential components of statistical inference and are frequently used to distinguish between statistical noise and scientific claims when interpreting experimental data in science.
- The null hypothesis, which is the statement being tested in a test of statistical significance, is typically a declaration of "no effect" or "no difference," and the test of significance is intended to evaluate the strength of the evidence against it

Answer:
Following are the organizational characteristics that explain the 100-year longevity of a company:
Explanation:
Selling Necessity Goods
Many of companies provide such goods and services which are essential for our everyday activities. Hence, people tend to buy from these companies as it is their routine to do so.
Laser-Sharp Customer Focus
These companies have always focused on the ever changing needs and demands of the customers and have worked accordingly. Hence their focus on customer service is the key to their success.
Willingness to Chart New Territory
Since customer needs are always evolving, all organizations celebrating centennials have taken significant gambles in order to expand their offerings. Steelcase, for instance, began as a furniture company but has recognized that the way people work has changed.
Ongoing Community Relationships
Long-lasting organizations also make their mark by giving back to the communities in which they’ve thrived. The GSUSA estimates that its members complete more than 75 million hours of community service annually.
These organizations have achieved so much because they have adapted their strategies to a changing world, and because they are always looking for ways to improve people’s lives. It is these traits that position them well no matter what the future holds.
Explanation:
Let’s explore one by one as proposed:
An oil cartel raises oil prices: all prices in the oil-related products will increase making it more expensive for companies to be able to afford employees. As the US economy is heavily based on oil import and consumption, the unemployment rate (let´s call it UR from now on) would increase. Countries that export more than import could benefit from this scenario.
The U.S. dollar gains value against foreign currencies: It would be more expensive to produce goods in the US as its currency becomes stronger. Hence companies could choose to produce overseas, increasing the UR. One of the factors that attract investments is a cheap currency, meaning that a company could operate there at lower costs than anywhere else.
American consumers expect higher income in the future: As fights about average salary would arise between employees and companies, igniting even sindicalization, its proper to think that the same as above could occur; companies could choose to produce overseas in countries less demanding of labor rights and income, such as China provinces (I would recommend for you to watch American Factory, a awarded Netflix documentary about that subject).
Brazil experiences economic growth and increases its demand for U.S. exports: as I said in the first alternative, a country that has increased or more expensive exports could benefit from that creating more jobs, in this case decreasing the UR. If Brazil demands more US products, more has to be produced by the country, which would mean more people employed in this attractive sector.
U.S. real estate values rise: to be honest, it only affects indirectly. As housing becomes more expensive, people have to work more to be able to afford housing. That would mean they seeking better-paying jobs or in the absence of those being homeless of at least unable to buy a home. We could argue that the UR would decrease because it becomes more expensive to afford housing and hence people would migrate more but that’s a long shot rationale.
Answer: Simple capital structure
Explanation: A company that does not have potentially dilutive or convertible securities in its capital structure, is said to have a simple capital structure. In a simple capital structure, the corporation finance its operation with common stock or non convertible preferred stock.
Hence , from the above we can conclude the right option is C.
