For each of the given, do the following:

First, draw the normal curve. Second, locate the z-value. Third,

indicate if the z-value is in the rejection region or in the

acceptance region.

1. z=2, 95% confidence, two-tailed

2. z=-2.68, 95% confidence, two-tailed

3. z=1, 95% confidence, one-tailed

4. z=1.33, 99% confidence, one-tailed

5. z=-4, 99% confidence, two-tailed

Task B: Create real-life situations where knowledge about the

concepts of random variables and probability distribution can be

applied.
