In order to study the relationship between fire damage (y, measured in thousands of dollars), the distance to the nearest fire station (x, measured in kilometres), and the Urban-Rural Classification of the house (URC, classified as “Urban' (U), “Semi-urban' (S), or “Rural'( R)), data from n 15 minor fires were analysed. For all fires in the study, firefighters attended the fire and were able to limit the damage to one area of the house. = The researcher fits two models to this data, using the R code below: x) Model 1: modeli Model 2: model2 Im(y lm(Y x + URC)
a) Explain the difference between observational and experimental studies. Which kind is this study?
b) In Model 2, how many indicator (or dummy) variables are required for the URC categorical variable? 1 ООООО 14 15
