0.0153 .01 One-tailed
0.0232 .05 Two-tailed
0.002 .01 One-tailed
Using the z-table, find the critical value (or values) for each of the following
Level of significance Type of test Critical value(s)
0.05 Two-tailed
0.01 Left-tailed
0.005 Right-tailed
0.01 Right-tailed
0.05 Left-tailed
0.02 Left-tailed

12. (16pts). Given the following information, determine the P-value. \
#12
Information 		P -value Reject (R) or Do not Reject (DNR) at
a = 0.05 		Reject (R) or Do not Reject (DNR) at
a = 0.01
The test statistic in a left-tailed test is z = -1.25
The test statistic in a right-tailed test is z = 2.50
The test statistic in a two-tailed test is
z = 1.75
With H a :p* 0.707,
the test statistic is
z = -2.75
