Definitions:

Significance Level

A threshold in hypothesis testing, typically denoted by alpha, indicating the probability of rejecting the null hypothesis when it is actually true.

Known Variance

In statistics, refers to a situation where the variance of a population is a known quantity, facilitating certain types of inference.

P(T<=t) Two-Tail

The probability that the test statistic T will fall in either tail of its distribution, assuming the null hypothesis is true, used in two-tailed tests.

Significance Level

A statistical measure that determines the threshold at which the null hypothesis is rejected, commonly represented by the alpha (α) symbol and set before the experiment.
