I bought 175 g pack of salami which had 162 g of salami as well.
The weight is never exact, buy a few packages and see if the are within a standard deviation of the listed weight.
confused by this.
to calculate a standard deviation OP would have to buy a few packets anyways.
if you maybe wanna buy 100 to find what the standard deviation is, by definition, only 68% of them will be within a standard deviation (assuming the weights are normally distributed)
