c) A company conducts a randomized block design of four different machines, W1, W2, W3, and W4. It was decided that 6 different operators would be used to compare the machines. The machines were assigned in random order to each operator. From the table below test the null hypothesis that the machines perform at the same mean rate of speed, at the 5% level of significance. Please provide the ANOVA table. Machine Operator 3 4 42.5 39.3 39.6 39.9 42.9 43.6 +a 39.8 40.1 40.5 42.3 42.5 43.1 40.5 + b 41.3 43.5 40.2 43.4 44.9 45.1 4 41.3 42.2 44.2 45.9 42.3 Replace letter a above with the 7th digit and b with the 8th digit of your Student ID No. 123
