A bottle cap manufacture with four machines and six operators wants to see if variation in production is due to the machines and/or the operators. Each operator is assigned to each machine with the following Analysis of Variance table.
Source Sum of Squares df Mean Square
Machines 114
Operators 215
Error 54
Total 383
using a 1% significance level, what is the decision for the machines?
- Do not reject H0; there is no difference in production based on machines
- Reject the H0; there is a significant difference in production based on machines
