Problem 10SE

The article “Modeling of Urban Area Stop-and- Go Traffic Noise” (P. Pamanikabud and C. Tha- rasawatipipat, Journal of Transportation Engineering, 1999:152-159) presents measurements of traffic noise, in dBA, from 10 locations in Bangkok Thailand  Measurements, presented in the following table, were made at each location, in both the acceleration and deceleration lanes.

 Location Acceleration Deceleration 1 78.1 78.6 2 78.1 80.0 3 79.6 79.3 4 81.0 79.1 5 78.7 78.2 6 78.1 78.0 7 78.6 78.6 8 78.5 78.8 9 78.4 78.0 10 79.6 78.4

Can you conclude that there is a difference in the mean noise levels between acceleration and deceleration lanes?
