Question
Apply the ANOVA with a single factor (operator) under control, with a confidence level of 90%, and answer the following
questions. Numerical results must be reported in scientific form with 2 decimal digits, for example 1.23e4.
Is there a systematic effect among operators?
What is the variance of the examined factor?
What is the value of the standard deviation related to the variability within the groups?
What is the value of the extreme of the one-sided confidence interval of the Fisher distribution?
In order to not identify systematic effects, should the variance ratio be greater or lower than the extreme value of the one-sided
confidence interval of the Fisher distribution?
