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.
Checks are stale after 6 months. The bank may or may not accept the check if it is over 6 months if it is a government check. These are almost always good (money is available to pay the check).Other checks are questionable as to the funds availability. If the chech has a expiration date, you'll have to get the issuer to reissued the check to you.tate of Michigan, check is dated 5-4-2009. Has it expired already?? How long do you have to cash/deposit a State Income Tax Check before it expires?? Thanks!!!
