Ethan Manufacturing Inc. produces floor mats for automobiles. The owner, Joseph Ethan, has asked you to assist in estimating maintenance costs. Together, you and Joseph determine that the single best cost driver for maintenance costs is machine hours. These data are from the previous fiscal year for maintenance costs and machine hours: Required: 1. What is the cost equation for maintenance costs using the high-low method? 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. What is the cost equation for maintenance costs using the high-low method? (Round "slope (unit variable cost)" to 2 decimal places. Include outliers in your calculations.) 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.) Required information [The following information applies to the questions displayed below.] The Air Force Museum Foundation has commissioned the purchase of 16 Four F Sixes, pre-World War II aircraft. They will be built completely from scratch to the exact specifications used for the originals. As further authentication, the aircraft will be made using the technology and manufacturing processes available when the originals were built. Each of the 16 airplanes will be flown to Air Force and aviation museums throughout the country for exhibition. Aviation enthusiasts can also visit the production facility to see exactly how such aircraft were built in 1938. Soren Industries wants to bid on the aircraft contract and asked for and received certain cost information about the Four F Sixes from the Air Force. The information includes some of the old cost data from the builders of the original aircraft. The available information is for the total accumulated time as the 1st, 8th, and 32nd aircraft, respectively, were completed. The data reflect a learning rate of 80%. equired: If Soren Industries expects that the manufacturing time and learning rate will be the same as it was in 1938, how many hours will it ake to build the 16 aircraft for the Air Force Museum Foundation? Assume also that the learning that took place in the 1930 s is no onger applicable, and that learning begins anew at 1,750 hours for the first unit. (Do not round intermediate calculations. Round your inal answer to the nearest whole number.)
