A researcher felt there might be a correlation between weather conditions and people’s mental health. In order to verify his conjecture, he obtained data on the number of mostly sunny days (x) in 2015 from 245 randomly selected cities in the nation and their corresponding citizens’ happiness indices (y). In other words, he wants to test if there is a statistically significant correlation between x and y. How should he carry out the analysis?
