A company is doing a hypothesis test on the variation of quality from two suppliers. They believe that one of the suppliers has a greater 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 2 H0:01 2502² HA: 0₁²>0₂² One of the sample standard deviation's is 2.9664 with a sample size of 21 The other standard deviation is 4.4166, with a sample size of 14. The test statistic (rounded to 4 decimal places) is = The p-value (rounded to 4 decimal places) is = O Fail to reject the null hypothesis - there is not enough evidence to support a meaningful difference in the variance of the suppliers. O Reject the null hypothesis - there is enough evidence is support a meaningful difference in the variance of the suppliers.
