Find the probability that a particular set of eight consecutive points will fall on one side of the center line for a process that is in control. these are independent. You may therefore compute the probability for a binomial distribution with π = 0.5 and n = 7. You would use n = 7 instead of n = 8 because the first point of the sequence is free to fall on either side, so the situation is really determined by the seven other points.)
