Answer #1

The level of significance is defined as the probability of rejecting a null hypothesis by the test when it is really true, which is denoted as α.

Since it is a probability, it is a value between 0 and 1.

The significance level or alpha tells a researcher how extreme results must be in order to reject the null hypothesis. Therfore it's best to choose the significance level before a decision rule can be formulated.

Therefore, all the options are correct.

Hope it helps! Feel free to ask any doubts in the comment section!

Choose the correct one Level of Significance, Alpha, is: *The procedural definition is: Alpha determines the cut off point, which is the threshold used to decide whether the test statistic is statistically significant. * The Type 1 Error definition is: Alpha is the risk of rejecting the Null Hypothesis even though it is true (as an equality). * All of the answers are correct * As an analogy alpha is: "Innocent, but found guilty".
