Final answer:
A greater than or equal to comparison in mathematics is symbolized by ≥, and is used in stating inequalities, forming hypothesis tests in statistics, and comparing magnitudes in physics.
Step-by-step explanation:
In mathematics, a greater than or equal to comparison is denoted by the symbol ≥, not =>. This symbol is used in inequalities to compare two values where the value on the left side is either greater than or equal to the value on the right side. For example, one might use an inequality symbol to show how two metric measurements are related, such as stating that the length of one side of a triangle must be greater than or equal to the length of another side.
When forming hypotheses for statistical tests, one would typically use symbols such as H or H₁ to denote the alternative hypothesis. This alternative hypothesis is often expressed using the symbols ≠ (not equal to), > (greater than), or < (less than). For instance, in a scenario testing whether a certain parameter is greater than a specific value, the null hypothesis (H₀) could be expressed as ≤ (less than or equal to that value) while the alternative hypothesis (H₁) would be > (greater than that value).
In the context of science such as physics, one can compare magnitudes using greater than or equal to. If the magnitude of force A must be equal to the magnitude of force B, this is expressed as a = b. However, if force A's magnitude must be greater than force B, it is represented with a > b.
