noise levels in dBA

The following table presents measurements of mean noise levels in dBA (y), roadway width inm(x1), and mean speed in km/h (x2), for 10 locations in Bangkok, Thailand, as reported in the article “Modeling of Urban Area Stop-and-Go Traffic Noise” (P. Pamanikabud and C. Tharasawatipipat, Journal of Transportation Engineering, 1999:152–159).

Construct a good linear model to predict mean noise levels using roadway width, mean speed, or both, as predictors. Provide the standard deviations of the coefficient estimates and the P-values for testing that they are different from 0. Explain how you chose your model.
