Although the alternative shows an increased weight, we compute power under a two-sided test.

Dixon's test compares the individual values obtained by a single operator or the mean values obtained by several operators, or yet differences between two results obtained by several operators; it is a two-sided test (LOPES, 2003).
Two different cases have been considered: Case 1 states that the two binomial parameters equal some specified value and yields a two-sided test, whereas Case 2 states that the two parameters are simply equal to one another and yields one-sided or two-sided tests.
based public-interest group Public Citizen says the rule should consider real-world roll dynamics rather than quasi-static testing and notes that the proposed rule ignores Congress's demand for a two-sided test.
Note that this is two-sided test and test statistics can be negative depending on the relative magnitude of q, [q.
In the case in which we use a simple null hypothesis with a composite alternative, and variation in the parameter values can be on both sides of the null value, then we have a two-sided test.
Clearly if a two-sided test of strength ([Alpha], [Beta]) is desired, the one-sided results should be developed by (numerically) replacing [Alpha] with [Alpha]/2.
The sample size was estimated using two-sided test of difference using a ratio of test group 1: test group 2: control group of 1:1:1, and a = 0.
Since this is a two-sided test, we obtain the critical Z value from Appendix table 7 as [+ or -] 1.
