1 from Math III REVIEWING NORMAL DISTRIBUTIONS AND Z-SCORES You will need: White board & marker Calculator Z-score Table FFM Sheet (eventually)

2 REMINDER:

3 a.) What data value corresponds to a z-score of 1.5?

4

5 Calculate the z-score for: a.) X = 65

6 Calculate the z-score for: b.) X = 90

7 Calculate the z-score for: c.) X = 82.5

8

9 Determine the X value which corresponds to the following z-scores: b.) Z = 0.75 HINT: You will need to work backwards to find X…plug values into z-score formula and solve for x.

10 Determine the X value which corresponds to the following z-scores: c.) Z = 1.9 HINT: You will need to work backwards to find X…plug values into z-score formula and solve for x.
