Question 453265
From the empirical, or 68-95-99.7 rule, the probability that one value will be more than 1 standard deviation above the mean is {{{(1-0.68)/2 = 0.16}}}.  Assuming independence of the values, the probability that all four values will be more than one standard deviation above the mean is {{{0.16^4 = 0.00065536}}}
