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 α = 0.1. A sample of 26 products were selected from Supplier 1 and a standard deviation of quality was found to be 5.9088. A sample of 12 products were selected from Supplier 2 and a standard deviation of quality was found to be 2.2813. Test to see if the variance in quality for Supplier 1 is larger than Supplier 2.
The correct alternative hypothesis is:
Round answers to at least 4 decimal places.
The test statistic is =
The p-value is =
The decision is to .
The correct summary would be: that the variance in quality for Supplier 1 is larger than Supplier 2.
