It is believed that the surface roughness of some carbon product depends on tive carbon material type used for that product. The following data were obtaired for He product surface roughness as a tunction of the carbon materiar type:

\table[[Cartion Mrterial Tyje,Sulfer Rorgtures],[1,0.5,0.55,035,356,,],[2,0.31,0.270.,0.8,2.18,0.56,02],[2,02,2.25,Q.12,,-,],[4,0.1,0.16,,,,]]

Given that the leas I significant difference between mean surface roughress ct carbon material types 2 and 3 is LSO=0279, it can be concluded that ifere ist significant difference between the means of these two types?
