H0 , test statistic, and p value 

 

please

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. Asample of 32 products were selected from
Supplier 1 and a standard deviation of quality was found to be 7.0155. A sample of 27 products were
selected from Supplier 2 and a standard deviation of quality was found to be 2.5345. 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.
Hg: 0
H;: 0:
Based on the hypotheses, compute the following:
Round answers to at least 4 decimal places.
The test statistic is =
The p-value is =
The decision is to Reject the null hypothesis
The correct summary would be: There is enough evidence to support the claim
quality for Supplier 1 is larger than Supplier 2.
