The data was collected to investigate whether there was a significant relationship
between the population living within 5km of a volcanic location and the years since
the last eruption, at 10 selected locations.

critical values of Spearman’s rank rs when n = 10.
Null Hypothesis: There is no significant relationship between the number of people
living within 5km of a volcanic location and the years since the last eruption.
Alternative Hypothesis: There is a significant relationship between the number of
people living within 5km of a volcanic location and the years since the last eruption.
Confidence level 0.10 (90%) 0.05 (95%) 0.01 (99%)
Critical value 0.44 0.56 0.73
