    The owner of an office building studies heating cost versus daily high temperatures. He records the following data:

    Temperature (deg C) @ Cost ($100)
    -------------------------------

    1 @ 9
    4 @ 5
    6 @ 3
    10 @ 2

    He proposes a regression equation to predict the cost of heating the building.

    What is the predicted heating cost for a day with a high temperature of 8 degrees C and what is the correlation coefficient?

    Solution Preview

    The Regression equation to predict the cost of heating will be
    <br>Y=aX+b
    <br>where Y is the predicted cost
    <br>X is the high temperature
    <br>a is the coefficient of the first variable (temperature) and
    <br>b is the intercept.
    <br>Our given data ...

    Solution Summary

    The soltuion addresses the fact that the owner of an office building studies heating cost versus daily high temperatures and his data recording.
