Left tailed test vs right tailed test
NettetUse this method to find the p-value for a one-sided z-test with the critical region in the right tail. In this testing scenario, the result is the p-value. For the apple example above, the z-table indicated that the area below z = 0.67 was 0.74857. Consequently, the area above that z-score is 1 – 0.74857 = 0.25143.

The region of rejection, on the other hand, is on both sides of the sampling distribution. 4- To determine whether there is any relationship between variables in a single direction, such as left or right, a one-tail test is employed. NettetFor left-tailed, it's just the CDF mentioned above. For right-tailed, it's the opposite: everything BUT the left-area, hence the 1 − F ( T). For two-tailed, it's slightly tricky. You're trying to create a rejection area of two symmetrical pieces.
