Steel rods coming out of a casting process vary in weight by a small amount due to random non- uniformities in the molten metal. The next 10 rods from a batch weigh 501, 620, 510, 613, 514, 518, 657, 503, 624, and 570 grams. Historically, the variance in the weight of each rod has been 1225 gram^2, If the historical variance is appropriate, what is the standard error of the sample mean of the weight of 10 rods, in grams? 3.50 11.07 O 15.55 1012
