pound are given below. Estimate the standard deviation of the entire population
with $siglev$PERCENT confidence.

The weights of a random sample of cereal boxes that are supposed to weigh 1
pound are given below. Assume that the weight is normally distributed. Estimate
the standard deviation of the entire population with $siglev$PERCENT
confidence.
