Answer:
c. Observational studies have both independent and dependent variables.
d. Observational studies can be used to test hypothesis.
Explanation:
Observational studies are ones in which a researcher makes observations about his thoughts and views. He observes the risk and other effects before actual test takes place. This is usually the initial phase of research where observations are made for suitability of certain things that are to be researched. There is initial feasibility test conducted to identify whether the further research process is beneficial or not.
Answer:
Hi nohelia
Explanation:
The defeat at the Alamo in 1836 was significant for Texas because it gave the Texans a reason for fighting for their independence. The small number of Texans that fought the war at Alamo were tortured and killed and this led to a greater stimulus for gaining independence from the rule of Mexico for the Texans.
The Battle of the Alamo (February 23 – March 6, 1836) was a pivotal event in the Texas Revolution. ... Buoyed by a desire for revenge, the Texians defeated the Mexican Army at the Battle of San Jacinto, on April 21, 1836, ending the rebellion.

Answer:
Using convenience samples to develop constructs and scales can be risky.
Explanation:
Convenience sampling refers to the process of gathering information from a sample that is conveniently available to the researcher (family members, friends in social media). This is not a random sampling method because not all of the members have the same probability to be selected.
- Using convenience samples to develop constructs and scales can be risky.
From the definition, we can say that using convenience samples to develop constructs and scales can be risky since <u>the information gathered by using this sampling does not necessarily represent the characteristics of the population (since it was not chosen at random).</u>
- It is a time-consuming process when there are a large number of respondents.
This is not a time-consuming process but is actually easier to gather information this way rather than by other methods.
- It is commonly used in the later stages of research.
This process is a gathering of information process and it takes place at early stages of the research
- The representativeness of the sample can be measured because sampling error estimates are not calculated
As we said before, this is not a random sample and therefore it is not necessarily a representative sample.
- It is commonly used to generalize results to the target population.
Although probably our sample shares some characteristics with our target population, this sampling is not used to generalize results to the target population.
If she wrote that Ming makes a monetary contribution to an artisan group that produces natural dye in Guatemala two areas would be affected Factors for production and the rest of the world via foreign interactions. Thus the correct answer is B.
<h3>
What are the factors of production?</h3>
The resources that make up the economy's structure and that people utilize to produce commodities and services are known as the factors of production.
Land, labor, capital, and small business development are the four divisions that economists use to classify the components of production.
Businesses can enhance production and produce things of greater quality and at lower costs, if they can boost the productivity of the factors of production.
Therefore, option B factors for production and the rest of the world via foreign interactions.
