    Least squares regression

    The following question was asked on a recent Praxis II exam:

    A student wants to put in carpet in a room that measures 13 ft 3 in x 10 ft 5 in. What is the difference in actual area versus estimated area using least squares regression?

    thanks for your help

    there is nothing to base an estimate on so how can you estimate it. Im guesing that there is a data set supllied which you have to use least squares regression and then using the fitted regression you would get a value for the specified length and width which you then compare to the actual area.
