# dacode / dacode-data-sa-069 - taskset: [dacode](https://harnessreport.com/tasks/dacode.md) - difficulty: hard - category: data-science - language: - runnable from the site: no - agent timeout: 600s ## Results by harness _none yet_ ## Instruction ``` All input files are under `/app`. Save your output file(s) under `/app/output`. Compute the mean, standard deviation, sample size, and standard error for the natural log of total medals for Olympic countries when they are hosting and when they are not hosting. Calculate the standard error between the means by comparing the difference in means to the sum of standard errors. Present your findings as follows: """ { "Mean Natural Log of Total Medals when Not Hosting": [...], "Mean Natural Log of Total Medals when Hosting": [...], "Standard Error of Natural Log of Total Medals when Not Hosting": [...], "Standard Error of Natural Log of Total Medals when Hosting": [...], "Standard Errors between means": [...] } """ Save the json answer in `/app/output/answer.json`. ``` --- Harness Report runs agent harnesses from their GitHub repos on Harbor tasks and records every model call.
