Webb24 nov. 2024 · Now, for the cases where H 0 is a simple null hypothesis, then the set of all possible type-I errors is just a singleton set. So, for that test, the level and type-I error are equal. e.g. suppose you're testing H 0: μ = 0 against H a: μ ≠ 0 Then, the level and type-I error will indeed be equal.

WebbAnswer to Solved 1. Alpha is the probability of committing a Type I. This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. WebbWe examine two types of problems to illustrate this. Unstructured testing problems arise typically (but not exclusively) when many outcomes are being measured. We consider the case of more than two hypotheses when a Bonferroni approach is being applied while for illustration we assume compound symmetry to hold for the correlation of all variables.

WebbTo calculate the probability of committing a Type I error, we first need to find the value of A. We know that fr(y) = (1/A)e-λy, where λ = 1 and y ≥ 0, so we can integrate fr(y) over the … Webb2 sep. 2024 · For example, a p-value of 0.02 reveals a 2% chance that you may reject the actual null hypothesis wrong. You can reduce this probability of committing a type 1 error achieving by lowering the value for p. For example, a p-value of 0.01 indicates that there may be a 1% chance of committing an error.
