2. Three adhesives are being analyzed for their impact on the bounding strength of paper in a
pulp and paper mill. The adhesives are each randomly applied to four batches. The data is
shown in table. Here, the three treatments are the adhesive (p = 3), and the number of
replications for each treatment is 4(r = 4). The completely randomized design is a balanced
one. Find a 95% confidence interval for the difference in the mean bonding strengths of
adhesive 1 and 3. Is there a difference in the means of these two adhesives?
Adhesive
type
Bonding Strength (kg) Sum Mean
Adhesive 1 10.2 11.8 9.6 12.4 44.0 11.000
Adhesive 2 12.8 14.7 13.3 15.4 56.2 14.050
Adhesive 3 7.2 9.8 8.7 9.2 34.9 8.725
135.1 11.258
3. In the furniture industry the quality of surface finish of graded lumber is an important
characteristic. Three factors are to be tested, each at two levels, for their impact on the
surface finish. Factor A is the type of wood: oak (level-1) or pine (level 1). Factor B is the
rate of feed: 2m/min (level -1) or 4m/min (level 1). Factor C is the depth of cut: 1mm
(level-1) or 3mm (level 1). For each treatment combination three replications are carried
out using a completely randomized design. Table 2 shows the surface finish for the eight
treatments. The larger the value, the rougher the surface finish. Find the sum of squares for
each of the main effects and interaction effects.

5. Explain in detail the difference between various types of matrix diagrams.
6. Suppose for a solid propellant experiment, the thrust force develops (coded data) from each
formulation (A, B, C and D) is as follows :
Batch of raw
material
Operators
1 2 3 4
1 A=14 D=6 C=10 B=8
2 B=4 C=14 B=10 A=19
3 C=18 B=11 A=22 D=7
4 B=14 A=20 D=5 C=16
