Question
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 more
than 3.8 cm is p and the probability that a randomly selected AN screw would measure
less 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 and
3.8 cm is:
Hint: Draw the curve of the Normal distribution and use its symmetry
O 1-p-q
O 1-p+q
O 1-2p
O 1-29
