Question details

Problem 3 An experiment is conducted to determine whether the firing oven temperature affects the mean density of a certain type of brick. Multiple bricks are fired at different oven temperatures and the density is measured. The experiment led to the following data (shown in the order in which it was collected) e Minitab for this problem observation Oven Temperature (o Brick Densit 113.1 164.1 113.7 1900 2000 1800 1800 1950 1950 1900 1950 1900 2000 2000 1900 1950 1900 2000 1900 1900 2000 1900 2000 1800 2000 2000 2000 2000 1800 1900 1800 4 146.7 208.3 89.5 147.1 80.8 115.7 183.6 106.0 137.1 108.5 85.2 94.6 133.7 121.3 104.4 141.5 155.5 126.8 138.3 181.7 142.3 124.3 110.2 108.2 10 12 13 14 15 16 17 18 19 20 21 23 24 25 26 27 28 (a) What is the response? What is the factor? How many levels of the factor are used? How many replicates were used? (b) Test the hypothesis that oven temperature affects the mean density of bricks. Use o -0.05. Does over temperature affect the density of mean bricks? Yes or No? (c) Which oven temperature(s) maximize the mean brick density? Which oven temperature(s) minimize the mean brick density? Use a 0.05
