Without specific details from Scenario 11-3, it's impossible to accurately determine the outcome of the Tukey-Kramer procedure. However, the Tukey-Kramer procedure is used to compare all possible pairs of means when the sample sizes are unequal and the overall level of significance is set for the family of comparisons, not for individual comparisons. Saying there is no significant difference between any pair of mean speeds is a conclusion that cannot be universally applied without specific test results.
