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.

We will reject the null when the p-value is smaller than the significance level. The p-value . of this test is 0.044, which is smaller than the levels at .10, .05, but larger than .01. So we reject the H when =0.10 and .05, but fail to reject the null when =.01. 25. a. T. Since the population has a normal distribution, we can use the Normal ...
