4. A firm’s accounting department analyses the
variability of weekly unit costs reported from its two factories, A
and B. A sample of 13 cost reports from factory A and 19 cost
reports from factory B were collected. The analysis shows unit cost
standard deviations equal to 7.2 for factory A and 6.7 for factory
B. Conduct a hypothesis test to determine whether the two factories
differ in terms of unit cost variability. Use the 5% level of
significance. What is your conclusion?
