1. Using the z table (Table E) find the critical value(s) for each of the following(2 points):

• = 0.04, two tailed test.

• = 0.03, right tailed test.

1. Consider the following P-values, critical values, or test values and determine if you would reject Ho or fail to reject Ho. Justify your decision.

• Critical Value = 2.175 and a test value of -2.190
• p = 0.0210 = 0.02

1. Consider the following scenarios and determine the p-value or p-value interval.

• t = -1.927, n=23, left-tailed
• t = 2.341, n=30, two-tailed
• z =1.79, right tailed
