Data of 120 Hotels in the Euro zone were collected and stored in the file Hotel with the following variables:

Location (distance from city centre in meters)

Wellness services ( \(1=\) yes, \(0=\) no)

Room size (size of a standard twin bed room in square meters)

Room price (price of a standard twin bed room in euros)

Develop a regression model to predict room price, based on the location, room size, and wellness service. Be sure to determine whether any interaction terms need to be included in the model.
