    Post can you help me with this problem?

    The Army is soliciting proposals for the development of a truck-launched antitank missile. Pentagon officials are requiring that the automatic sighting mechanism be sufficiently reliable to guarantee that 95% of the missiles will fall no more than 50 ft of their target or no more than 50ft beyond. What is the largest value of s compatible with that degree of precision? Assume that the random variable X, the horizontal distance a missile travels, is normally distributed with its mean m equal to the length of the separation between the truck and the target.

    please put solution so i can review it. thank you.
