False. The choice between a one-tail and a two-tail test is relevant in hypothesis testing because it affects how you assess the significance of your results.
A one-tail test focuses on detecting an effect in one direction (either greater than or less than a certain value), while a two-tail test assesses effects in both directions (whether the value is significantly different from the target value, either greater than or less than). This distinction influences the critical values and the p-value calculation, affecting the conclusion drawn from the test.
A one-tail test focuses on detecting an effect in one direction (either greater than or less than a certain value), while a two-tail test assesses effects in both directions (whether the value is significantly different from the target value, either greater than or less than).
