Required Problem 3-14 High-Low Method; Scattergraph Analysis [LO2] [The following information applies to the questions displayed below.] Travis Metals heats copper ingots to a high temperature by placing them in a large oven. The heated ingots are then run through a shaping machine that forms them into wire. Due to the length of time it takes the oven to heat up, it is never turned off. When the ingots are placed in the oven the temperature is raised to a higher level. Once they are done being heated the oven temperature is turned back down until a new batch of ingots is ready to be heated. The following information shows the ingots processed and the power costs over the past 10 months. Month Ingots Power Cost January 142 $6,780 February 122 $5,780 March 112 $5,680 April 132 $6,280 May 162 $7,280 June 152 $6,880 July 102 $5,280 August 92 $4,480 September 82 $4,680 October 72 $3,680 Problem 3-14 Part 1-b 1-b. Do power costs appear to be related to the number of ingots processed in a month? Yes No
