All hypotheses are tested using a four-step process:. A random sample of coin flips is taken, and the null hypothesis is then tested.

If, on the other hand, there were 48 heads and 52 tails, then it is plausible that the coin could be fair and still produce such a result. In cases such as this where the null hypothesis is "accepted," the analyst states that the difference between the expected results 50 heads and 50 tails and the observed results 48 heads and 52 tails is "explainable by chance alone.
