True or False A researcher can increase the likelihood of re

True or False

A researcher can increase the likelihood of rejecting a false null-hypothesis by:

1-- True False  Decreasing alpha (e.g., use .01 instead of .05)
2-- True False  Using a treatment that is more extreme.
3-- True False  Increasing the error variance.
4-- True False  Increasing the sample size.
5-- True False  Using a one-tailed test rather than a two-tailed test

Solution

1-- False  Decreasing alpha (e.g., use .01 instead of .05)
2-- True Using a treatment that is more extreme.
3-- False  Increasing the error variance.
4-- True   Increasing the sample size.
5-- True Using a one-tailed test rather than a two-tailed test
