Refer to Exercise 10.CE.25 about VO₂ max and the thickness of grey matter in the superior frontal lobe of the brain. A statistically significant negative linear association was found between these two variables. In the article, the author also looked at linear associations between VO₂ max and eight other regions of the brain. Two more significant associations were found for a total of three significant associations of VO₂ max with areas of the brain at the α = 0.05 level of significance. Using what you know about multiple tests on the same data and conclusion errors, detail why the significant finding between VO₂ max and the superior frontal lobe may give you pause.

Data from Exercises 10.CE.25 

Some studies have suggested that aerobic activity can benefit brain development and cognition in growing children (Chaddock-Heyman, 2015). It is thought that the higher your aerobic activity as measured by VO₂ max (mL/kg/min), the thinner the cortical grey matter in the superior and anterior frontal lobes (measured with an MRI). A sample of 40 children (ages 8–10 years) was recruited from Illinois to participate in the study. Use the data found in VO2MaxS-FLobe to answer the questions.
