25. Suppose there is an experiment to compare fuel economics for two types of similarly equipped diesel mini-trucks. In this experiment, 15 Volkswagen and 10 Toyota trucks were used in a 90-kph test. If the Volkswagen trucks averaged 17 km/liter with s=1 km/liter and the Toyota units averaged 12 km/liter with s=0.8 km/liter. It is desired to know if it can be sufficiently said that Volkswagen trucks exceed similar Toyota counterparts by 4 km/liter at 5% significance level.
