2. Calculate the mean absolute percentage error (MAPE) for the cost equation you developed in requirement 1.
Complete this question by entering your answers in the tabs below.
Calculate the mean absolute percentage error (MAPE) for the cost equation you developed in requirement 1. (Do not round
intermediate calculations, with the exception of MAPE for each month, which should be rounded to three decimal places. Input
your final answer as a percentage rounded to 1 decimal place (i.e., 0.054 = 5.4%). Include any outliers in your calculations.)
