A bottle cap manufacturer with four machines and six operato
A bottle cap manufacturer with four machines and six operators wants to see if variation in production is due to the machines and/or the operators. The ANOVA table follows. What are the degrees of freedom for the machines, operators, & errors? What is the critical value of Ffor the machine treatment effect at the 1% level of significance? What is the critical value of Ffor the operator block effect at the 1% level of significance? What is the mean square for machines, operators, and error? What is the computed value of F for the machines? For the operators? Test the hypothesis that all operators are equally productive. State your decision in terms of the null hypothesis.
