hey believe that one of the suppliers has a different variance than the other upplier and would like to perform a hypothesis test to support their claim. Both distributions are normal, and the populations are independent. use a = 0.01 "ο: στ2 = σ2 Ho:01 Supplier 1: standard deviation = 3.54, Sample size = 24 Supplier 2: standard deviation = 8, Sample size = 29. he test statistic (rounded to 4 decimal places) is = he p-value (rounded to 4 decimal places) is = O Reject the null hypothesis - there is enough evidence is support a meaningful difference in the variance of the suppliers. O Fail to reject the null hypothesis - there is not enough evidence to support a meaningful difference in the variance of the suppliers.

Question
A company is doing a hypothesis test on the variation of quality from two suppliers. They believe that one of the suppliers has a different variance than the other supplier and would like to perform a hypothesis test to support their claim. Both distributions are normal, and the populations are independent. use a = 0.01 Ho: σ12- σ2 2 HA:0 1 Supplier 1: standard deviation = 3.54, Sample size = 24 Supplier 2: standard deviation = 8, Sample size = 29. The test statistic (rounded to 4 decimal places) is = The p-value (rounded to 4 decimal places) is = O Reject the null hypothesis - there is enough evidence is support a meaningful difference in the variance of the suppliers. O Fail to reject the null hypothesis - there is not enough evidence to support a meaningful difference in the variance of the suppliers.
