  • Power and type 2 error

    The power of a hypothesis test is the probability of not making a type II error, that is, the probability of rejecting a false null hypothesis. So Power=1 - P(type II error) = 1 - beta.

  • Effect of significance level on likelihood of errors

    278554 What is the effect of the significance level (alpha) on the likelihood of 1) rejecting the null hypothesis, and 2) committing a type I error or a type II error? Why does the significance level differ among industries?

  • Probability of type II error and the error of margin

    If P=4/5, What is the probability of type II error for this procedure? 2. A sample of 350 orders for takeout at a local pizzeria found out that the average cost of order was $22 with s=$14.
