How to write the formula of Sum of Squared Deviation with SD and n in R?

I'll use $\sigma$ for SD to avoid confusion with SSD: If $\sigma = (\frac{SSD}{n-1})^{0.5}$, then $\sigma^2 = \frac{SSD}{n-1}$. Therefore: $SSD = \sigma^2 (n-1)$

Do we need hypothesis testing when we have all the population?

dying, you probably don't care about the current population, but about a more abstract population of "potentially existing humans" or "all humans in history" of which you take people alive today as a sample
