Question
( a ) Use a statistical package to find the value of the linear correlation coefficient between year and NYC temp. (b) Is the correlation
( a ) Use a statistical package to find the value of the linear correlation coefficient between "year" and NYC temp.
(b) Is the correlation significant? Explain the reason for your answer
(c) If the correlation is significant, what does it imply about the trend in temperatures?
(d) Find the equation for the least squares regression (LSR) line
(e) Interpret the meaning of the slope of the LSR line.
(f) Based on the equation of LSR line, what is the "best predicted" value for the NYC Annual Average Temperature for 2013? How accurate is the prediction?
(g) Can we use this LSR line equation to predict the Annual Average Temperatures for the future? Explain.
