Question 1142049: Question text
Let's look again at the semi-trucks traveling between Baltimore, Maryland and Alexandria, Virginia. We said that the probability that a truck exceeds the speed limit is 75%. Suppose a random sample of 5 trucks are selected.
What is the standard deviation σ of the probability distribution?

standard deviation = square root( 0.75 * (1-0.75) / 5) = 0.1936
