Extracted text: Skrifleg dæmi The consumer association decided to conduct a study comparing three different types of baking powder (A, B and C) in order to check if there was a difference in their effectiveness. The study was carried out in such a way that six cakes were baked with each type of baking powder. The volume of the cakes was measured and the following sizes were also calculated SST = 2039.72, MSg = 82.40 a) Fill in the following square sum table (you should write six numbers in the table): analysis of degress of variance freedom ave week sums SSTR = MSTR = SSE = MSE = 82.40 SST = 2039.72 b) Check with an appropriate hypothesis test whether there is a difference in the average volume of the cake depending on the type of baking powder used. Show all steps 6. Use a = 0.05. If you could not complete MSTR in the table above, use MSTR = 500.
