Question
Some tests were carried out on a newly designed carburetor. Four variables were studied as follows: Variable A: tension on spring B: air gap Low Narrow C: size of aperture Small D: rate of flow of gas Slow A B C The immediate object was to find the effects of these changes on the amount of unburned hydrocarbons in the engine exhause gas. The following results were obtained. 11+ +1 + +1 1 1 1 1 + + 1 +++ ++1 + + D +1+1+11+ High Open Large Rapid + Unburned Hydrocarbons 8.2 1.7 6.2 3.0 6.8 5.0 3.8 9.3 It was hoped to develop a design giving lower levels of unburned hydrocarbons. Perform an analysis of variance to give suggestions on how the experimental objectives may be achieved. Use 5% level of significance. Provide the settings that will optimize the desired result.
