{15pm} A research engineer studied the time efciency of tour construction methods (A, B. C. D} for an electronic component. Four technicians were selected for the study. The construction process produces fatigue such that the required construction time by the technicians increases as they change from one method to another regardless oi the order of construction methods. The engineer used a Latin square design with columns as 'technician' and row as 'time period". The construction methods were randomized to the mmcians and time periods according to the Latin square arrangement. The values are construction times in minutes required for the component with the construction method indicated in parentheses. Time period Technician 2 3 4 1 90 (C) 96 (D) 84 (A) 88 (B) 2 90 (B) 91 (C) 96 (D) 88 (A) 3 89 (A) 97 (B) 98 (C) 98 (D) 4 104 (D) 100 (A) 104 (B) 106 (C) Please construct the ANOVA table. At significance level 0.01, do the construction method, technician and experiment time period have significant impacts on the time efficiency?
