Using the estimation results, compute a 99% confidence interval for the coefficient on zi. Give an economic interpretation of the result.

Your friend works for an estate agency. He would like to understand what
characteristics influence monthly rents of properties. Therefore, he plans to estimate
the following regression model:
P₁ = αo + α₁x₁ + α₂²¡ + αzW; + Uj,
for i = 1,...,93, where the individual variables are defined in the table below:
Variable
Description
