Question

4. You have been tasked with the design for the beds in the evacuation center. The 20 average individual in the population is 5, 6" tall with a standard deviation of {(A+ B) / C} inches. Decide what length (in inches) to design the bed in order to accommodate 95% of the population. (assume population height is normally distributed, and that accommodation is based on bed length only) 5. After some research, you have learned that there are many people in the civilian population who are blind. Explain how you would recreate your Warning Display System to accommodate this portion of the population. (Obviously, your new design can be more than just visual) lo

Answer 1

4)

P(X < x) = 0.95

mean = 5'6'' = 66 inch

P(Z < z) = 0.95

z = 1.645

hence

x = 66 + 1.645 *sd

here you have not provided the values of A,B and C

sd = (A + B)/C

and put in above equation to get length
