The decision to reject the null hypothesis using the Z test is made by comparing the Z score needed to reject the null hypothesis (based on the significance level or alpha) to the actual Z score calculated from the sample data. This comparison determines whether the sample data are significantly different from what is expected under the null hypothesis.
