Question
A company is doing a hypothesis test on the variation in
quality from two suppliers. Both distributions are normal,
and the populations are independent. Use a = 0.01. A sample
of 30 products were selected from Supplier 1 and a standard
deviation of quality was found to be 4.0931. A sample of 24
products were selected from Supplier 2 and a standard
deviation of quality was found to be 3.1165. Test to see if the
variance in quality for Supplier 1 is larger than Supplier 2.
What are the correct hypotheses? Note this may view better
in full screen mode. Select the correct symbols in the order
they appear in the problem.
