An ecologist investigated the relationship between soil moisture content (as a percentage) and the population density of a rare wildflower species (measured in plants per square metre) using a sample of 14 distinct plots. A Spearman's rank correlation was conducted on the collected data.
The calculated value of rs r_s\,rs was 0.593. The critical value for a two-tailed test where p≤0.05 p \le 0.05\,p≤0.05 and N=14N = 14N=14 is 0.538.
Write a significance statement for the correlation analysis performed on this data.
