Power is the probability that a study will reject the null hypothesis. The estimated. probability is a function of sample size, variability, level of significance, and the. difference between the null and alternative hypotheses. Similarly, the sample size. required to ensure a pre-specified power for a hypothesis test depends on variability, level of significance, and the null vs. alternative difference.
Nature of stale check. Stale check is a check that is presented to be cashed or deposited at a bank six months or more after the date it was written.
Best Answer: It's called a stale check or money order. Usually anything over 6 months old is hard to cash. However, it should still be good as the money hasn't been paid against the MO. Take it to the bank. What they may do is accept it and hold it until they are paid (the MO has cleared).
