Solution:
Tukey's HSD is given by formula:
where q = Table value from Tukey's HSD Q table.
n = Number of values.
MSwithin = Mean square within groups.
Decision Rule: If absolute difference between means is greater than HSD calculated by above formula, then we say difference is significant.
Thus correct option is: b. greater than the HSD.

8. Tukey's HSD test A Aa 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...

An engineer wants to know if the mean strengths of three different concrete mix designs differ significantly. He also suspects that slump may be a predictor of concrete strength. Slump is a measure of the uniform ity of the concrete, with a higher slump indicating a less uniform mixture.The accompanying data represent the 28-day strength (in pounds per square inch) of three different mixtures with three different slumps.
