Q1 A study on the effect of different lubricating oil on fuel economy in car engines is investigated. The fuel economy is measured using the brake-specific fuel consumption after the engine running for 15 minutes. There are five different cars selected for the study and the experiment is conducted using randomized completely block design (RCBD) as in Table Q1. Table Q1 Car Oil 2 3 4 5 0.532 0.617 0.498 0.363 0.317 0.411 1 0.581 0.588 0.547 2 0.677 0.566 0.593 0.579 3 0.514 0.482 (a) Explain whether the effect of lubrication oil on fuel economy in car engines is differs at a 0.05 level of significance.
