In mining hоles аre оften drilled in rоck using speciаl bits. As holds get deeper аdditional rods are added to to the bit so that drilling can continue. As the hole gets deeper the drilling progress slows, due to a variety of factors. including the mass of the drilling rods that are strung together. The business problem is to determine whether the drilling will be faster using dry (forced air) or wet (forced water) drilling techniques. Data were collected for 50 holes of each type including the time to drill a 5 ft segment starting at different depths, the depth of the hole when starting the 5 ft segment, and whether dry or wet drilling was used. The (partial) results of a regression table are 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 SUMMARY OUTPUT Regression Statistics Multiple R 0.834345 R Square Adjusted R Square Standard Error 0.750085 Observations 100 ANOVA df SS MS F Significance F Regression 2 8.13248E-26 Residual 97 54.57482 Total 99 179.6004 Coef St. Error t Stat P-value Intercept 5.90 0.169765 34.78241 1.4E-56 Type 2.10 0.150017 14.03308 4.38E-25 Depth 0.005228 0.00104 5.028928 2.26E-06 What is the average difference in time to drill a 5 ft segment if the wet drilling technique is used?
