could you help giving me explanation on these problems ? Thank you .

Question 9 Problem 4. An engineer plans to conduct an experiment on a resistor mounted on a ceramic plate. The goal of the experiment is to assess the impact of four geometrical shapes of the resistor on the current Not yet resistor's noise. Four plates are considered for the experiment which were provided by four different suppliers. Only three resistors can be mounted on one plate. Points out of Which design would you recommend for this experiment? 10.0 P Flag question A. Latin square design B. Randomize Complete Block Design O C. Balanced Incomplete Block Design O D. Factorial design with blocks Question 10 Regarding Problem 4. The experimenter conducted the experiment using the appropriate design. She computed the ANOVA summary table using the R software and the 'zov' function. The incomplete table is Not yet shown below. nswere Points out of 5.0 Df Sum Sq Mean Sq F value Flag question ? 3 0.35 0.12 8.45 9 3 0.47 0.16 11.32 Residuals 0.0 0.01 What is the observed value of the test statistic for the factor under study?
