A special task force of a military unit requires that the recruits not be too tall or too short. Suppose 12% of the applicants are rejected because they are too tall and 18% because they are too short. If the height of an
applicant is normally distributed with a mean of 69.4 inches and a standard deviation of 3.5 inches, determine
the heights that define whether an applicant is accepted or rejected.

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
