Statistics

An engineer suspects that the cutting speed (in inches) and feed rate (inches/minute) affect the surface finish of the metal part. For study the engineer gathered four cutting speeds and 3 feed rates and conducted a 2 factor experiment to obtain the data in Table with 3 replications. Make ANOVA at α = 0.05 to test for the significance of all possible effects.

Table

Feed Rate
Cutting Speed	0.10	0.20	0.30
100	54, 60, 65	79, 68, 80	99, 88, 94
200	98, 89, 94	98, 106, 90	100, 98, 108
300	109, 98, 89	100, 108, 94	99, 82, 102
