Answer #1

The Tukey's Honestly Significant Difference(HSD) procedure it requires equal sample size and equal group means.

False.

The Tukey's HSD procedure is used to check if particularly certain effects are significantly different from each other when the original null hypothesis is rejected. In this test we do require the sample sizes to be equal. However, if sample sizes are different we can perform another test called the Tukey-Kramer method.

The difference of the group means will be used in the test statistic to perform the test. If the group means are equal then the test statistic will be equal to zero and the null hypothesis will be automatically accepted.

10. Tukey’s HSD test Sleep apnea is a disorder characterized by pauses in breathing during sleep. Children who suffer from untreated sleep apnea often have behavior problems, including hyperactivity, inattention, and aggression. A common treatment for pediatric sleep apnea is the surgical removal of enlarged tonsils and adenoids that are obstructing the airways. Suppose researchers at a sleep clinic are interested in the effect of surgical treatment for pediatric sleep apnea on aggressive behavior. They study 11 children without sleep...
