Question

An engineer is interested in the effects of cutting speed (A), tool geometry (B), and cutting angle (C) on the life (in hours) of a machine tool. Two levels of each factor are chosen, and three replicates of a 2^3 factorial design are run. The results are as follows: Treatment Replicate A B C Combination I II III - - - (1) 22 31 25 + - - a 32 43 29 - + - b 35 34 50 + + - ab 55 47 46 - - + c 44 45 38 + - + ac 40 37 36 - + + bc 60 50 54 + + + abc 39 41 47

1. An engineer is interested in the effects of cutting speed (A), tool geometry (B), and cutting angle (C) on the life (in hours) of a machine tool. Two levels of each factor are chosen, and three replicates of a 23 factorial design are run. The results follow: Treatment Replicate A B C Combination I II III - - - (1) 22 31 25 + - - a 32 43 29 - + - b 35 34 50 + + - ab 55 47 46 - - + c 44 45 38 + - + ac 40 37 36 - + + bc 60 50 54 + + + abc 39 41 47 (a) Estimate the factor effects. Which effects appear to be large?

6.2 An engineer is interested in the effects of cutting speed (A), tool geometry (B), and cutting angle (C) on the life (in hours) of a machine tool. Two levels of each factor are chosen, and three replicates of a 2^3 factorial design are run. The results are as follows: Treatment Combination (1): 22, 31, 25 a: 32, 43, 29 b: 35, 34, 50 ab: 55, 47, 46 c: 44, 45, 38 ac: 40, 37, 36 bc: 60, 50, 54 abc: 39, 41, 47 (a) Estimate the factor effects. Which effects appear to be large?

00:01 So here our standard error, standard error effect will be here under root 1 by n into 2 to the power k minus 2 into s square.
00:21 Here our value of s square is given in the question is 30 .17.
00:30 Now we'll put the value then we'll be getting here under root 1 by n is how here 3 into the into 2 into 3 to the power minus 2 into we'll put the value of s which is 30 .17...
