For the given null (H) and alternative (H1) hypotheses, compute the maximum value of z that leads to a rejection of the null for a one-sample left-tailed z-test for a mean with a significance level of a = 0.10. Ho: u = 15 H:< 15 Use software to find the value of z to at least three decimal places. You may find one of these software manuals useful. Z = -

For the given null ( ?0 ) and alternative ( ?1 ) hypotheses, find the positive value, ? , and the negative value, −? , that define the critical region (rejection region) for a one-sample two-tailed ? ‑test for a mean with a significance level of ?=0.040 . ?0:?=5,?1:?≠5. Use software to find the values of ? to at least three decimal places. You may find one of these software manuals useful. −?= ? ?=?

Suppose that a forester wants to see if the average height of lodgepole pines in Yellowstone is different from the national average of 70 ft. The standard deviation lodgepole pine height is known to be 7.1 ft. The forester decides to measure the height of 23 trees in Yellowstone and use a one-sample z-test with a significance level of 0.01. She constructs the following null and alternative hypotheses, where u is the mean height of lodgepole pines in Yellowstone. Hou...
