I want an easy explanation step by step

1 1. If a hypothesis is rejected at the 5% level of significance, it a. will always be rejected at the 1% level b. will always be accepted at the 1% level will never be tested at the 1% level d. may be rejected or not rejected at the 1% level ANS: D 12. For a one-tailed test (lower tail) at 93.7% confidence, Z = a. -1.86 b. -1.53 C. -1.96 d. -1.645 ANS: B 13. Read the Z statistic from the normal distribution table and circle the correct answer. A one-tailed test (upper tail) at 87.7% confidence; Z = a. 1.54 b. 1.96 c. 1.645 d. 1.16 ANS: D 14. In a two-tailed hypothesis test the test statistic is determined to be Z = -2.5. The p-value for this test is a. -1.25 b. 0.4938 c. 0.0062 d. 0.0124
