TLF ID L2343
Check whether a machine is packing most matchboxes with an acceptable number of matches (40–60 matches per box). Look at boxplots made after taking samples of 100 matchboxes. Analyse the data and identify whether results are within the tolerance range. Adjust the machine's scoop size or speed (if needed) to make it work correctly. Interpret boxplots made from new samples. Notice that the machine variables affect the median and range of sample values. This learning object is a combination of two objects in the same series.
