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 26 products were selected from Supplier 1 and a standard deviation of quality was found to be 6.0042. A sample of 25 products were selected from Supplier 2 and a standard deviation of quality was found to be 1.802. Test to see if the variance in quality for Supplier 1 is larger than Supplier 2.

Expert Solution
Step 1

The question is about hypo. testing

Given :

Randomly selected no. of products from supplier 1 ( n1 ) = 26

Std. deviation of quality of products from supplier 1 ( s1 ) = 6.0042

Randomly selected no. of products from supplier 2 ( n2 ) = 25

Std. deviation of quality of products from supplier 2 ( s2 ) = 1.802

Level of signif. ( α ) = 0.01

 

To find :

Test that var. in quality for supplier 1 is larger than supplier 2
