In Exercises 3 – 8, determine whether a normal sampling distribution can be used. If it can be used, test the claim about the population proportion p at the level of significance a.

3. Claim: p 6 0.12; a = 0.01. Sample statistics: = 0.10, n = 40

4. Claim: p Ú 0.48; a = 0.08. Sample statistics: = 0.40, n = 90

5. Claim: p _ 0.15; a = 0.05. Sample statistics: = 0.12, n = 500

6. Claim: p 7 0.70; a = 0.04. Sample statistics: = 0.64, n = 225

7. Claim: p … 0.45; a = 0.05. Sample statistics: = 0.52, n = 100

8. Claim: p = 0.95; a = 0.10. Sample statistics: = 0.875, n = 50
