Question

1. For a two-tailed test, the region of rejection is on the left tail, and the region of nonrejection is on the right tail. True or False? Why?

2. Type I error means that we fail to reject H0 when it is indeed false. True or False? Why?

3. Type II error means that we accept H0 when H1 should be accepted. True or False? Why?

4. By specifying significance level = 0.01, the Type II error is guaranteed to be smaller than 1%. True or False? Why?

5. Power equals to one minus the level of significance . True or False? Why?

1. For a two-tailed test, the region of rejection is on the left tail, and the region of nonrejection is on the right tail. True or False? Why?

false , the region of rejection is in both tail , and the region of nonrejection is in middle

2. Type I error means that we fail to reject H0 when it is indeed false. True or False? Why?

false , type I error is reject Ho when Ho is true

3. Type II error means that we accept H0 when H1 should be accepted. True or False? Why?

true!

4. By specifying significance level = 0.01, the Type II error is guaranteed to be smaller than 1%. True or False? Why?

false , alpha dont have nothing in common with guaranteed to be type II smaller or greater than ...

5. Power equals to one minus the level of significance . True or False? Why?

false

power is equal to one minus betha that is probability of type II error
