- A Type I error occurs when a treatment has an effect but the decision is to fail to reject the null hypothesis. True or False?Type-II error is? A. Rejecting the null hypothesis when it is actually true B. Not rejecting the null hypothesis when its actually false C. Accepting the null hypothesis when its actually false D. Rejecting the alternative hypothesis it is actually falseIf we fail to reject the null hypothesis when the alternative hypothesis is true, we have made a type Il error. type a error. correct decision. type B error. type I error.
- Conduct a test of the null hypothesis for both independent variable and interpret your finding. You do not have to calculate anything by hand here; use excel output.Suppose a researcher comes up with a new drug that treats Borderline Personality Disorder (BPD). She assigns some patients who have BPD to receive a placebo and others to receive the new drug. The null hypothesis is that the drug will have no effect. 1. In this case, what would be the Type I error? In this case, what would be the Type II error?if we do not reject the null hypothesis when the null hypothesis is in error, then we have made a a.Type β error b.Correct decision c.Type I error d.Type II error
- A hypothesis test was conducted to see if a new HIV vaccination reduces the risk of contracting the HIV virus. The implication of a Type II error from the clinical trial is that the vaccination will not be approved when it indeed does reduce the risk of contracting the HIV virus. true falseSuppose the null hypothesis, H0, is: a patient is not sick. State the Null and Alternative Hypothesis. Which type of error has the greater consequence, Type I or Type II?If we fail to reject the null hypothesis when the alternative hypothesis is true, we have made a O type a error. O type B error. O type I error. O type II error. O correct decision.
