In your own words, write your conclusions regarding which islands, if any, differ from one another with regard to the means of finch beak depths????
Explanation / Answer
Decision rule : If P value < 5% or 1% or 10%, then there is significant difference between given different pairs
By observing all p values < 1% and 5%
AT 1% or 5%, we conclude that there is no significant difference between given different pairs
At 10% level, there is only difference between Tenerife and El Hierro , since p value = 0.051 < 0.1
