Use R programming language to answer and please so show the code as well.

A paper manufacturer studied the effect of three vat pressures on the strength
of one of its products. Three batches of cellulose were selected at random
from the inventory. The company made two production runs for each pressure
setting from each batch. As a result, each batch produced a total of six production
runs. The data follow. Perform the appropriate analysis.

Table is below

Batch Pressure Strength
A 400 198.4
A 400 198.6
A 500 199.6
A 500 200.4
A 600 200.6
A 600 200.9
B 400 197.5
B 400 198.1
B 500 198.7
B 500 198.0
B 600 199.6
B 600 199.0

C 400 197.6
C 400 198.4
C 500 197.0
C 500 197.8
C 600 198.5
C 600 199.8

as to compare the pressure wats the anova is used .From the results of anova p value for batch and pressure are less than 0.05 .hence Batch and Pressure both difer significantly ..

For pairwise comparisons tukeys test is used

PLEASE USE R PROGRAMMING TO SOLVE THIS AND PASTE A COPYABLE CODE Photoresist is a light-sensitive material applied to semiconductor wafers so that the circuit pattern can be imaged on to the wafer. After application, the coated wafers are baked to remove the solvent in the photoresist mixture and to harden the resist. Here are measurements of photoresist thickness (in kA) for eight wafers baked at two different temperatures. We want to see whether different temperatures make difference. The data...
