Final answer:
The correct way to write an alternative hypothesis in mathematics, which involves inequality or not equal symbols, is exemplified by the expression (A1 > 4) for a hypothesis that A1 is greater than 4.
Step-by-step explanation:
The correct way to write an argument in the context of hypothesis testing in mathematics is by using inequality symbols or the not equal symbol. When writing the alternative hypothesis, it is typically denoted with H₁ or H and uses symbols such as < (less than), > (greater than), or ≠ (not equals). For example, if the alternative hypothesis states that a certain value A1 is greater than 4, it would be correctly written as (A1 > 4).
