Find the P-value for a left-tailed test with a test statistic of z = -2.23. Decide whether to reject H0 if the level of significance is α = 0.01. From the normal table z = -2.23 is P= 0.0129 which is the area in the left tail. Since 0.0129 > 0.01, you should fail to reject H0. Find the P-value for a two-tailed test with test statistic of z = 2.14.
