Please help me with the following problem! It is
1. The effects of developer strength (factor A) and development time (factor B) on the density of photographic plate lm are being studied. Two strengths and two development times are used, and four replicates for each treatment combinations are run. The results (larger is better) are as follows. Table 1: Data for Problem 1 Development Development Developer T'me (m'nutes) Developer T'me (m'nutes) Strength 1 1 Strength 1 1 10 14 10 14 0 1 4 6 1 5 4 2 7 7 2 3 6 8 4 2 5 7 (a) Determine the effects for factor A, factor B, and the interaction of factor A and factor B. (10 points) (b) Obtain a main effects plot for factors A and B. (10 points) (c) Obtain an interaction plot. (10 points) ((1) On the basis of the results of parts a-c, what conclusions can you reach concerning the importance of factor A, factor B, and the interaction of A and B on the development time? (5 points)
