Question 537110: The number of patients needing a bed at any point in time in the pediatrics unit of a hospital is . Find the middle 50% of the number of beds needed (you may consider fractions of beds). Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! The number of patients needing a bed at any point in time in the pediatrics unit of a hospital is N(19.2,2.5) . Find the middle 50% of the number of beds needed (you may consider fractions of beds).

Draw a picture of the problem on a normal curve:
Find the z-value with a left tail of 0.25:
invNorm(0.25) = -0.6745
Find the corresponding x-value using x = zs+u
x = -0.6745*2.5+19.2 = 17.51
-----
By symmetry, find the upper limit:
x = 0.6745*2.5+19.2 = 20.89
