The production of AN screws states that the mean length for AN screws is 3.2 cm. Also,it is known that the probability of a randomly selected AN screw would measure morethan 3.8 cm is p and the probability that a randomly selected AN screw would measureless than 2.8 cm is q. Suppose that the production of AN screws is normally distributed,then the probability that a randomly selected AN screw will measure between 2.6 cm and3.6 cm is:Hint: Draw the curve of the Normal distribution and use its symmetry1-291-2pO 1-p+qO 1-p-q
