Using the mоdel аbоve we becаme curiоus if drill type аnd depth interacted so that the slope of the drilling time with depth changed depending on the type of drilling. To test this a new model was made that included a type*depth term to examine the interaction between time and depth. A partial regression output is below. Y = Drill time of a 5 ft segment in minutes Depth = Depth of the hole in ft when the 5 ft segment was begun Type = Wet = 1, Dry = 0 Depth*Type = Depth interaction with Type ANOVA df SS MS F Significance F Regression 3 7.43385E-25 Residual 96 Total 99 179.6004 Coefficients Standard Error t Stat P-value Intercept 6.002882 0.215886 27.80576 1.02E-47 Type 1.909135 0.305309 6.253116 1.11E-08 Depth 0.004459 0.001474 3.025864 0.003182 Type*Depth 0.001538 0.002084 0.737888 0.462382 What conclusion below can be reached?
