• B)n1 = n2 = 10 with a pooled variance of 100
• C)n1 = n2 = 20 with a pooled variance of 10
• D)n1 = n2 = 20 with a pooled variance of 100

Degenerate

In mathematics and physics, it refers to a less general or simpler class of an entity or phenomenon with less symmetry or fewer distinctions.

Optimal Solution

An Optimal Solution refers to the best possible outcome or decision from a set of alternatives, often identified through processes like optimization in mathematics and computer science.
