An apartment management company wants to explore the consequences of allowing residents to have multiple dogs. They would like to find out whether the number of dogs predicts resident ratings. They would also like to control for the year the apartment complex was built because thaty might also affect the resident rating. They have collected data on several of their existing complexes. For each complex, they have counted the number of dogs currently living in the complex, the year the complex was built, and the average rating for that particular complex. They would like to perform a multiple regression on these variables to predict resident ratings. See data below. These data are the same as the previous question.

Number of dogs Year of facility Rating (out of 5)
54 1975 2
31 1964 3.5
0 2015 4.8
11 2011 3.8
73 1964 2.3
23 2016 3.7
0 2015 4.7
49 1989 2.7

The effect of Number of Dogs has a p-value .05, which means it is .
