A company is doing a hypothesis test on the variation of quality from two suppliers. Both distributions are normal, and the populations are independent. use a = 0.01 H0:01²502² 2> HA: 01 >02 2 The standard deviation of the first sample is 3.8419 with a sample size of 36. 5.51 is the standard deviation of the second sample with a sample size of 19. The test statistic (rounded to 3 decimal places) is = O Fail to reject the null hypothesis O Reject the null hypothesis
