i need the complete anova table for this. 3 factor factorial crd. and i want to know why N-1 =53? . i thought N should be 27 since observation is 27?

edit= what you mean by missing?

QUESTION 5 The yield of chemical process is being studied. In this study, the experimenter chooses three levels of temperature and three levels of process that might affected to this response. However, only nine runs can be made in each day. Three days in specific month were randomly selected to run an experiment. The experimenter felt that all interactions among the factors should be studied. The total yields recorded for the two replicates of the design are given as follows: Day 1 Temperature 250C 260C 270C Day 2 Temperature 250C 260C 270C Day 3 Temperature 250C 260C 270C Pressure Low Medium High 171.7 176.9 179.0 169.5 175.2 182.0 172.4 178.9 183.8 172.8 178.9 182.8 170.1 178.9 186.2 174.3 180.4 187.1 172.5 179.1 181.0 170.2 177.2 185.2 173.8 179.2 184.8 A partial ANOVA table is shown below: Source of Variation Sum of Squares Pressure Temperature Day Pressure* Temperature Pressure Day Temperature Day Pressure* Temperature Day Error Total 305.041 14.667 13.285 15.363 2.512 0.550 1.414 7.555 360.387 Degree of Freedom 2 2 2 4 4 4 8 27 53 a) Which factor(s) is random and which is fixed? (2 marks) b) State the expected mean squares for Temperature Pressure and Day QUESTION 5 The yield of chemical process is being studied.
