Save your output file(s) under `/app/output`. It is observed that the beaks of G. scandens birds on Daphne Major appear to have become deeper. Assuming that the means of two groups of data are the same, you need to calculate the probability of observing the difference in means as per the instructions in tips.md. Under the null hypothesis that the means of the two groups are equal, calculate the probability (p-value) of observing the actual difference in means or a more extreme value.Write the calculated results in the format specified in sample_result.csv into the result.csv file. ``` --- Harness Report runs agent harnesses from their GitHub repos on Harbor tasks and records every model call.
