Why don’t we calculate the average of an entire given population instead of computing confidence interval to estimate the population mean?

Usefulness of the confidence interval
Well, you can calculate all the proportions for which the chance of seeing 1 black and 4 white sheep is greater than 5%. That would be all the "reasonable proportions" based on your observation. This is a 95% confidence interval. Is that true? I'm having a lot of trouble getting my head around the functorial definition and yours, which seems to be around conditional probability.
