I'm having trouble answering #13.

Question 11-14: To decrease noise emitted from their laptops, Dell engineers have created four new designs for digital computer circuits. After creating 5 prototypes of each type circuit, the circuits were installed, and the noise level observed. A summary of the data is as follows: Circuit Design A B C D 5 5 5 19.2 70 36.6 79.8 1 1. In context of this problem, construct the fixed-effects ANOVA model. yij = M + Cut Cis Use 12. Given SSW = 2948.8 and TSS=14990.8, finish filling in the ANOVA table below: Source df SS MS F 24 Between Groups 13 12042 4014 21.178 Within Groups 2918.8 84.3 Total 1419 90. 8 13. Using the ANOVA table in Problem #12, is there a significant difference between noise observed and type of circuit used? Use a = 0.05 and the critical region method 25
