A local production company has two independent lines that make the plastic cards for debit cards.Both lines use control charts to ensure they run to target specification and both lines have been in control for the last month.Recently, however, the quality manager has noticed that one of the lines has many more items being rejected for the measurement concerning the width of the card. The manager decides the problem must be with the variability in production on the line and decides to run a test.He samples 25 items from production line 1 and discovers the standard deviation is 2.2 mm, whereas the sample of 25 items from line 2 has a standard deviation of .52 mm.At the .10 level of significance is there a significant difference in the variability of the width of the card between the 2 lines?
