A sample of 2500 men was found to have a normal distribution with their height. The average height is 70 inches with a standard deviation of 1.4 in. How many men had an average height below 68 inches?

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.

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it
