Question

Read the z statistic from the normal distribution table and circle the correct answer. A one-tailed test (upper tail) at a 123 level of significance, a. 1.645 b. 1.54 C. 1.96 O d. 1.16
When the hypotheses Ho μ z 100 and Ha μ < 100 are being tested at a level of significance of o, the null hypothesis will be rejected if the test statistic z is a. -za O c. 100
For a one-tailed test (upper tail) with a sample size of 900, the null hypothesis will be rejected at the 05 level of significance if the test statistic is a. less than 1.645 0 b. less than-1.96 c.greater than or equal to 1.645 d. less than or equal to -1.645
For a two-tailed test with a sample size of 40, the null hypothesis will not be rejected at a 5% level of significance if the test statistic is 0 a. between-1 .96 and 1 .96, exclusively Ob. less than 1.645 0 c, greater than-1 .645 d. greater than 1.96
Which of the following does not need to be known in order to compute the p-value? a. knowledge of whether the test is one-tailed or two-tailed O b. the value of the test statistic O c. the level of significance O d. All of these are needed.
