Computing power and sample sizes

You want to compare average funding per investment round for games companies versus advertising companies. You begin by computing the power of a two sample t-test.

Three things have been loaded for you:

  • ads_acquired_avg_funding - (pandas Series) The average funding of each acquired advertising company
  • games_acquired_avg_funding - (pandas Series) Same, but for game companies
  • ads_games_cohensd - (Number) Cohen's d (standardized effect size) for advertising versus games company's

The function needed to compute power has been imported from statsmodels.stats.power.
