Boeing manufactures two planes for long-distance travel. Below is data on these two planes and their respective annual engine maintenance cost per plane:  747 777 In production since: 1969 Avg maintenance cost = $15.8 million Standard deviation of cost = $2.7 million In production since: 1995 Avg maintenance cost = $7.5 million Standard deviation of cost = $1.5 million Boeing executives are promoting the 777 because of it’s consistent low maintenance cost. Comment on Boeing’s claim using the numbers provided; that is, use statistics in your answer.[Group1]
