Make a scatterplot using year as the explanatory variable and temperature as the responsevariable.

The leastsquares regression lineis

temperature=7.8+(0.0111year)

What would you predict for the annual average temperature for 2014 based on this line? Report your answer in degrees to two decimalplaces.

temperature =

Celsius

The predicted temperature from the leastsquares regression equation for 2014 is

within degrees of the actualtemperature.

The correlation between these variables is =0.675. What percentage of the variation in temperature can be explained by the straightline dependence on year? Round your answer to the nearest wholepercent.
