Hello
I want to get the answer for this question for ( Transportation Planning ) class ASAP. The table to use the valuse inside it.
Thanks
TABLE 10.3.1 FHWA NOISE STANDARDS (a) Design noise leve/land-use relationships Land-use category Design noise Description of land-use category level, L10 60 dBA Tracts of land in which serenity and quiet are of extraordinary significance and serve an important public need, and where the preservation of those qualities is essential if the area is to contine serve its intended purpose. Such areas could include amphitheater particular parks or portions of parks, or open spaces which are dedicated or recognized by appropriate local officials for activities requiring special qualities of serenity and quiet. (exterior) 70 dBA Residences, motels, hotels, public meeting rooms, schools, churches libraries, hospitals, picnic areas, recreation areas, playgrounds, active sports areas, and parks.

FC VC SP
mean 2,465 alpha 4 5
SD 127 beta 6 3
A 20 34
FC + VC * units = Sell price * units (when we break even)
units = FC / (SP - VC)
For simulating the fixed cost (following normal with mean 2465 and sd 127), in excel write the formula norm.inv(rand(),2465,127)
For the variable cost, write the formula beta.inv(rand(),4,6, 20,32)
For the selling price, write the formula beta.inv(rand(),5,3, 34,92)
fourth column will have units as FC/ (SP - VC). drag the 4 columns to 100,000 observations. 100,000 simulations yielded the average units as 57
