MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Source SS MS Fo.05 Four different coatings are being considered for corrosion protection of metal pipe. The pipe will be buried in three different types of soll. To investigate whether the amount of corrosion depends either on the coating or on the type of soil, 12 pieces of pipe are selected. Each plece Is coated with one of the four coatings and buried in one of the three types of soil for a fixed time, after which the amount of corrosion (depth of maximum pits, in 0.0001 in.) is determined. The data appears in the table. Error Soil Type (B) Total What can you conclude for HaA? 65 46 51 O Fail to reject Hoy. The data suggests that there is a coating effect. 57 O Reject Hog. The data does not suggest that there is a coating effect. Coating (A) O Fail to reject Hoy. The data does not suggest that there is a coating effect. 48 50 O Reject Hoy. The data suggests that there Is a coating effect. SU What can you conclude for Hos? (a) Assuming the validity of the additive model, carry out the ANOVA analysis using an ANOVA table to O Fail to reject Hog- The data does not suggest that there is a soil type effect. see whether the amount of corrosion depends on either the type of coating used or the type of soil. O Fail to reject Hog- The data suggests that there Is a soll type effect. State the appropriate hypotheses for the coating effect. O Reject Hog. The data suggests that there is a soil type effect. Hay: at least one a # 0 Reject Hog. The data does not suggest that there is a soil type effect. OH: 1 = 12 = ] = 04-0 Hax: no a, = 0 (b) Compute the model parameters. (Round your answers to two decimal places.) Hay: all a's = 0 Han: at least one a = 0 State the appropriate hypotheses for the soil type factor.
