Calculate an average or typical time. If I would just use the median (or other "normal" types of calculating an average), for example $23:59$ and $00:01$ would yield $12:00$ when it should $00:00$. Is there a better method?

Is a weighted average, assuming the weights sum up to one, always smaller than the unweighted arithmetic average? As if the weights are smaller than one the weighted mean is a convex combination of the individual points. Is there any condition on the individual observation for the statement to hold true?

If we have a $3\times 3$ matrix of information where the row totals describe the total goods produced by a particular company and the column totals provide the total for a particular type of good for all companies how would I create a weighted average that tells me the average percentage Good A takes up, out of all production, for all companies? Is it necessary to weigh by company if the total number of products produced is, say, $10,50$, and $20$?
