Explanation / Answer

1) is there a significant effect due to side-toside effect? what is your basis for the concluson?

p-value = 0.0475 < 0.05 , there is a significant effect due to side-toside effect

2) is there a significant effect due to air jet pressure? what is our basis fo rthe conclusion?

p-value = 0.01844 < 0.05 , there is a significant effect due to air jet pressure

3) is there an interaction effect between side to side effect and air jet pressure? what is your basis for the conclusion?

p-value =   0.1817 > 0.05 , there is no interaction effect between side to side effect and air jet pressure
