OK, so we have: WBACG532xSAM53yyy And for x we have values of, 1, 5, 7 or 8 so far, and for yyy we have 492, 540, 544, 593, 599, 618, 621 and a "mine is in there also" So the mean value is 572 with a standard deviation of 48 with This is saying about 2% will have a value of less than 472, or about 2% will have a value of more than 672. Assuming we have a normal distribution of samples. That is reasonable considering C&D stated that there were 200 made. 95% confident the mean is within the range of 537 to 608. I would put a range of about WBACG532xSAM53472 to 53672 give or take a few in either direction. |
