The latitude (L) and the average temperatures in February (T) in degrees Celsius (∘C) of 10 world cities were measured. The calculated least squares linear regression model for this data was: T=35.7−0.713(L) a. The slope is which interprets b. The relationship between latitude (L) and the average temperatures (T) of these 10 world cities is This means c. If in fact the average temperature (T) for these 10 world cities is 10 degrees Celsius (∘C) for a latitude of 40 , the residual is which means we have
