<PRE><B>Question 327288</B>
A regression was done for 20 cities with latitude as the explanatory variable (x) and average January temperature as the response variable (y). 
-------------------------------------------
The latitude is measured in degrees and average January temperature in degrees Fahrenheit. The latitudes ranged from 26 (Miami) to 47 (Duluth) The regression equation is T(x) = 49.4 - 0.313x
================================================ 
The city of Miami, Florida has latitude 26 degrees with average January temperature of 67 degrees Fahrenheit. 
1. What is the estimated average January temperature for Miami? 
T(26) = 49.4-0.313(26) = 41.26
------------------------------
2. based on the regression equation, what is the residual?
Residual = Observed-Estimated = 67-41.26 = 25.74
------------------------------

====================================
A) Estimated January temperature is 36.88 and the residual is 11.88
B) Estimated January temperature is 41.3 and the residual is - 25.7
C) Estimated January temperature is 36.88 and the residual is - 11.88
D) Estimated January temperature is 41.3 and the residual is 25.7 </PRE>
