Please answer the following essay question with 5 or more sentences:
What are the advantages of taking a random sample instead of surveying an entire population?

Answers

Answer:

Answer is below

Step-by-step explanation:

Simple random sample advantages include ease of use and accuracy of representation. No easier method exists to extract a research sample from a larger population than simple random sampling. Selecting subjects completely at random from the larger population also yields a sample that is representative of the group being studied. This provides lack of bias towards the subject of the survey. It's overall more efficient, faster, and pushes the idea of simplicity through surveys.

Answer:

Simple random sample advantages include ease of use and accuracy of representation. No easier method exists to extract a research sample from a larger population than simple random sampling. It offers a chance to perform data analysis that has less risk of carrying an error. ... There is an equal chance of selection. ... It requires less knowledge to complete the research. ... It is the simplest form of data collection.

Answers

Answer:

I believe x = 12

Step-by-step explanation:

If the triangles were similar then they would have the same angle measures.

Steps:

Add angle K and L: 90 + 54 = 144

Subtract the added angles from 180 to find angle J: 180 - 144 = 36

Angle J is similar to angle X so, divide 36 by 3: 36/3 = 12

x = 12
