The circumference of a particular species of tree was thought to be different depending on certain geographical factors. A random sample of 60 trees is selected in Sequoia National Forest, where it is found that sample mean = 6 meters with a standard deviation = 3 meters. A second random sample of size 40 is independently selected in Yellowstone National Forest, and it is found that sample mean = 4 meters with a standard deviation = 2 meters. Let H1 and H, represent, respectively, the true mean circumferences of trees the two- from Sequoia National Forest and Yellowstone National sample t procedures are safe to use. Forest respectively. Assume The researcher tests the following hypotheses: H. - I. H + I.
