  2. # 1 • First draw a picture (should look something like the minitab below, but not in z score scale). • The next thing we do is find the z score. • We know . • Now, either using minitab or a table (like appendix d in the back of the book) we find the percentage. • We get 0.1587 or 15.87%. • Minitab plot to the right.

  3. # 2 • First draw a picture (should look something like the minitab plot below, but not in z scores scale) • The next thing we do is find the z scores. • We know. • Now, either using minitab or a table, we find the percentage. • We get 0.5492 or 54.92%. • Minitab plot to the right.
