The issue of the amount of difference between a population with an unknown mean (which you sample from) and a null hypothesis population (µ₀= 8) is the issue of A) hypothesis testing or confidence intervals B) Type I and Type II errors C) .05 or .01 $\alpha$ level D) effect size.

Question

Quizplus · Accepted Answer

The issue described pertains to effect size, which measures the magnitude of the difference between a population mean (from which a sample is drawn) and a null hypothesis mean. This is not directly about the mechanics of hypothesis testing, error types, or significance levels, but rather about quantifying the strength or importance of the observed difference.
