WebbThe risk of making a Type I error is the significance level (or alpha) that you choose. That’s a value that you set at the beginning of your study to assess the statistical probability of … A perfect test would have zero false positives and zero false negatives. However, statistical methods are probabilistic, and it cannot be known for certain whether statistical conclusions are correct. Whenever there is uncertainty, there is the possibility of making an error. Considering this nature of statistics science, all statistical hypothesis tests have a probability of making t…

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 entire range of y to find A: ∫ 0 ∞ y … WebbThe probability of committing a Type I error (chances of getting it wrong) is commonly referred to as p-value by statistical software.
