Show transcribed image text 34.2 test. A firm that manufactures engines for racing snow machines gathers data from all of its plants. The table below gives the distribution of the life span of the engines (in numbers of months) for the entire firm. Table 34.1 gives you the expected life span in months. Table 34.2 gives you the actual life span of 448 engines from the Quebec factory. Is there a difference in the distribution of life spans for the engines manufactured in Quebec versus the firm's overall distribution? Table 34.1. Engine life span (in months). Table 34.2.
