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.
The check was 16 months old, which is what is known as a stale dated check. As I have been told, checks older than 90 days are never supposed to be cashed or credited. When I spoke with the bank manager at Sovereign Bank, he said he was really shocked, that cashing a 16 month old check was, as far as he knew, illegal. The check had originally had a stop payment placed on it.
