D For the next 2 questions: Four different machines are being considered in an assembly plant. It is decided that 6 different operators are to be used in a randomized block experiment. The machines are assigned in a random order to each operator. The amount of production time (in seconds) were recorded. A randomized block model is fit to these data. of Sum Sq Mean 5q Machine 3 15. 92 5.308 Operator 42.09 B. 417 Residuals 15 23.85 1.590 Run (Cmd-Enter) You should assume that any scripts or data that you put into this service wim public, Privacy policy Question 26 3 pts Find the p-value for testing whether there is a significance difference among the mean production times for the 4 machines. Question 27 3 pts Estimate the operator variance component. Il app.honorlock.com is
