Question

For this exerdise, round all regression parameters to three decimal places It is common in large cities for people to travel to the center city and then walk to their final destination. In: is given partially in the accompanying table.t Distance D 300 500 1000 1500 2000 Percent P walking at least D feet 60 40 18 (a) Make a model of P as an exponential function of D p = 26.400 × 1.582D p = 84.726 x 0.999D O p = 72.154 x 0.821D p = 5.899 x 1.001 60.531 × 0735D (b) What percentage of pedestrians walk at least 180 feet from parking facilities? (Use the model f 99.99 (c) When models of this sort are made, it is important to remember that many times they are only into to lou this as an accurate model for very

Explanation / Answer

from a) exponential function

p(D)=84.726*(0.999)^D

the percentage of pedestrains walk atleast 180 feet from parking facilities is given by

P(180)=84.726*(0.999)^180

=70.762730755%

  

c)P(0)=84.726*(0.999)^0

=84.726%
