Bird Species from Temperate Regions Must Cope with Relatively Short

Multiple Choice

Bird species from temperate regions must cope with relatively short breeding seasons. A study examined the relationship between blood testosterone level (ng/ml) and the duration of the egg-laying period (months) in temperate bird species. The following scatterplot displays this relationship, after taking the logarithm of each variable:
What does this scatterplot reveal?

A) A weak negative linear association between the logarithm of egg-laying duration and the logarithm of testosterone level
B) A weak positive linear association between the logarithm of egg-laying duration and the logarithm of testosterone level
C) No association at all between the logarithm of egg-laying duration and the logarithm of testosterone level
