a. For each situation, find Z(critical).

b. For each situation, find the critical t score.

c. Compute the appropriate test statistic (Z or t) for each situation:

1. μ = 2.40  = 2.20

σ = 0.75 N = 200

2. μ = 17.1  = 16.8

σ = 0.9

N = 45

3. μ = 10.2  = 9.4

σ = 1.7

N = 150

4. P_u = .57 P_s = 0.60

N = 117

5. P_u = 0.32 P_s = 0.30

N = 322
