i. The pooled variance t-test ii. The non-pooled t-test (Welch-Satterthwaite method) iii. Either of the above iv. None of the above(b) Recall that the folded F-test compares the variance of two inde- pendent samples. The null hypothesis is that the two variances are equal. Suppose the p-value for the folded F-test is 0.003. Then what would be the appropriate t-test to use to compare the two samples
