Ball weights

[dmalone]

Using the 3 ball weights posted below and our 3 weights I ran a 1000 piece random sample in Mintab based upon the average & standard deviation of the 6 to estimate the population....

Stem-and-leaf of Weight l N = 1000
Leaf Unit = 0.0010

Summary:
Min ~ .610 lbs
Mean ~ .651 lbs
Max ~ .706 lbs

More than 6 samples will improve the estimate of the population however it looks fairly tight...
