• A) \(\frac { 5 ( y + 5 ) } { 2 y }\)
• B) \(\frac { 2 y } { 5 ( y + 5 ) }\)
• C) \(\frac { y + 5 } { 10 y }\)
• D) \(10 y ( y + 5 )\)

Definitions:

Sampling Variability

The natural variation in statistics (such as the mean) that occurs from one sample to another.

SRS

Simple random sampling, a basic probabilistic method ensuring each member of a population has an equal chance of being included in the sample.

Statistically Significant

Refers to a result that is unlikely to have occurred by chance alone, according to a predefined significance level, often indicating a strong evidence against the null hypothesis.

Hypotheses

Plural of hypothesis; propositions or assumptions made for the sake of argument that are tested through research or experimentation to be proven or disproven.
