Activity:

     You are working in the quality control department for the Stuporific Drug Company, manufacturers of Zapuwol.  You obtained samples of pills made by both the day shift and the night shift workers at the company and did a chemical analysis of each pill to determine the amount of active ingredient present.  (Each pill is supposed to contain 5 mg of the ingredient.)  Here are your findings:

     Day shift:     4.7     4.7     4.9     5.1     5.1

     Night shift    0.0    0.0    5.0    10.0    10.0

1. Determine the means and medians for each shift and compare these with the desired level of 5 mg.  Which shift’s average was closer to the target?

2. If you needed to take a Zapuwol pill, on which shift would you prefer the pill to have been manufactured?  Why?
