chosen after selecting the sample and calculating the test statistic.

based on the sampling distribution and chosen level of significance.

specified by a panel of expert statisticians elected annually.

Solution

The decision rule is:specified so as to support the researcher\'s alternative hypothesis.

Since,   The choice of a decision rule depends, on the nature of the data, what one needs to decide about the data, and at what level of significance.

The decision rule is a statement that tells under what circumstances to reject the null hypothesis. The decision rule is based on specific values of the test statistic (e.g., reject H₀ if Z > 1.645). The decision rule for a specific test depends on 3 factors: the research or alternative hypothesis, the test statistic and the level of significance. Each is discussed below.
