Yes, there is a statistically significant difference between the absorption data of black walnut trees and maple trees due to difference in values of absorption.
<h3>Determine if there is a statistically significant difference?</h3>
Yes, there is a statistically significant difference between the absorption data of black walnut trees and maple trees because the average carbondioxide absorption of black walnut is 7.26 while on other hand, the average carbondioxide absorption of maple tree is 5.82. We can see there is big difference of absorption data between black walnut trees and maple trees.
So we can conclude that there is a statistically significant difference between the absorption data of black walnut trees and maple trees due to difference in values of absorption.
